Empires of the Undergrowth News

We're now much closer to our first major update, featuring leafcutters. As well as continuing development of the update to completion, we've been dealing with quite a lot of meta-requirement systems in the meantime, such as subtitles (which will be a long-overdue feature beginning with this update). Once we're at a point where we can get meaningful feedback from our closed testing group, we will release it to them and that will soon give us a good idea of how long it will take to correct any detected issues. As always, our policy is to not give vague guesses on release timing, only solid dates once we're certain of them - but we're feeling good about the current pace of things and the rate at which the remaining task list is being ticked off.

There's been plenty of good visual things finalised and ready to show off over the past month - some of which show off some leafcutter mechanics. So let's have a look at some of the fun things that await when you introduce Atta cephalotes to your Formica ereptor colony!



Rainforests are hugely diverse - they're the most diverse land habitats on Earth; rich in speciation and sheer variety of solutions to evolutionary problems.



We've worked hard to make sure that's reflected in the fauna, but just as importantly the flora of our Ecuadorian setting. Here's a closer look showing some of the plant life in a recent art pass of level 3.1 - the first leafcutter level.







Leafcutters gain their nutrition from the fungus they grow in their gardens, sprouted from decomposing leaf cuttings harvested from the surface. The minors, mediae and majors collect cuttings and drop them off in designated chambers.

The minims (the smallest leafcutters) then take the leaves to the brood chambers where the fungus grows (this includes the queen tiles). The fungus will grow as leaves are added, then diminish as it is used up by new hatchings and tile placement – it then produces waste which must be managed. The short video below demonstrates this process.

Placing a pheromone trail marker near a plant will draw leafcutters assigned to it – they’ll see the plant as a harvestable food source, just like seeds or dead creatures in previous levels. The major, mediae and minor workers climb the stem, taking time to cut a chunk of leaf before taking it to a drop-off point in the nest. As detailed above, the minims will then take it to the fungus gardens.

The leaves will diminish visually as they are harvested by the leafcutters, giving a physical indication of when the resources are used up and new grazing pastures must be found.

Below is a rather pleasing close-up of this process happening.

https://www.youtube.com/watch?v=Cfg9T-q_VKk



This pair of pictures shows the near-completed interface modifications needed to bring leafcutters to the game. You’ll notice a new resource bar at the top of the screen. Green on the left represents fungus available to spend, grey is space available on the nursery tiles to grow fungus, and red on the right is used fungus that needs to be disposed of.



Over time, the fungus produces waste which must be removed and taken to special chambers (right of the first picture). The refuse chambers will have a detrimental effect on nearby brood chambers, so it’s wise to build them a good distance away from where your ants pupate and travel – non-minim ants walking through them will take a speed and attack de-buff as well as suffer damage for a time. This represents the disease that the real-life counterparts of our leafcutters aim to avoid by having dedicated refuse areas. Waste decays and disappears over time – faster for upgraded refuse tiles.





"Yes, yes, I know how to use a trowel!" - Scientist #2

The colony’s current home is not suitable for the next set of tests. In order to continue the experiment, the scientists will need to relocate the queen to a new Formicarium. She and a few of her workers will be relocated into this new setting, which has a few… extra features.



When this process happens, the colony will need to leave its food, construction and territory behind. However, it will be rewarded an amount of royal jelly for each territory point and item of food (spent or unspent). This can be spent on the new leafcutter majors or any upgrades and improvement the colony needs – this will help it get quickly back up to speed. All upgrade paths and minor improvements will also carry over.



The change will happen just before you move on to tier 3 – in the level selection dialogue there will be a button which will unlock the 3rd tier levels.





Last month, John posted some select notes from the source control (update log) of Empires of the Undergrowth, to give a little insight into what each of our developers has been doing. He’s made another post along these lines in the meantime, and as before we think it’d be fun to go through some of these notes and give a little extra commentary to them. We encourage you to read John’s original thread, and indeed sign up for our official forums whilst you’re at it!

• Changed the way ramps work when the tide rises (ants no longer fall through) – this was the cause of a hardware-specific crash that had plagued us for quite some time. As it turned out, some ants when caught on ramps were falling through them to infinity – and in certain situations this caused a game crash on some systems. A tricky one to fix, but perseverance got us there! This has already been implemented in the current playable build of the game.
  
• Tweaked uber resistances – in certain situations and with certain colony setups, some uber creatures had become practically invulnerable. This was an oversight and not intentional – although uber creatures are still extremely tough and deliberately so, there should be fewer situations where they are unbeatable. There’s plenty more tweaking work to be done on freeplay, and indeed once the leafcutter update is done John will be focussing on another freeplay pass.
  
• Set tabbed minimaps to always have home nest on the left – the coming updates will enable multiple true colonies in a limited sense. To access their minimaps, there has been a new system made to keep them accessible as tabs behind the player’s own.
  
• Ants that enter an enemy colony are now tracked– similar to above, you’ll be invading some other nests if you dare.
  
• Subtitles for all levels added – a long-overdue feature and one important for accessibility (and localisation) but one which needs a lot of grunt work. We’re at a point now where we want this functionality to be there going forward – it’s important to the future of the game and our community as a whole.
  
• Tweaked the dissolve in various ways – this refers to the visual effect when a foreground object needs to be partially obscured by dithering so you can see through it. It’s particularly important for the Ecuador levels, which have a lot of low-growing foliage.
  
• Preparing in-game text for translation – localisation is important for the success of a game. We’re getting there.
  

Looking through the things you guys do with the simple tool of Photo Mode (F9 by default) or otherwise is always an excellent palate cleanser after writing one of these newsletters. It refreshes the soul. By default, F12 will take a screenshot in Steam.

A valiant effort to ward off an uber beetle in this colourful shot from MasterAntlion

Our first newsletter of 2019! A bright, shiny, spanking new year – and it’ll be a big one for ants. After the holiday break the guys are back to working on the 3rd tier Formicairum levels. We’ve also released a couple of glitch-fixing patches in the meantime to deal with some widespread issues. Firstly, let’s get to what’s ready to show from 3.1 and 3.2.

A Formica ereptor queen from MorPacke



Salticidae is a widespread family of spiders that can be found all over the world. They travel widely in search of food and do not spin webs to catch prey – instead they actively hunt, using powerful back legs to pounce on unsuspecting prey before it had the chance to react. For this reason, they are known as the jumping spiders.

The species that will appear in Empires of the Undergrowth is Psecas viridipurpureus, a South American resident. It’s brightly-coloured, and even a little cute if you can see past its arachnid form! It sits patiently, turning its body from left to right to allow its highly specialised eyes to scan the environment. When it spots a likely prey item, it perfectly calculates the distance it needs to travel, then pounces.

The harvestmen are a diverse group of arachnids (order Opiliones). They may colloquially be called daddy longlegs. Although superficially spider-like in appearance, they differ greatly from true spiders in several ways. They have no distinct separation in thorax and abdomen, and only a single pair of eyes. They are further distinguished from spiders by often being generalist, opportunistic feeders rather than predators – a rare trait in arachnids. They might hunt, scavenge or graze. The South American species in our game is sometimes called the “Jason’s mask harvestman” because of the distinctive hockey mask-like pattern on its back.

In-game, the harvestman keeps its body at a safe distance from attackers with its long legs – although the legs themselves can be quite brittle. It may have a cursory nibble at a trail of leafcutter ants, but it will make a quick retreat if it suffers an injury such as the loss of a leg.

Bam! Hunting behaviour



Leafhoppers are small insects that subsist by consuming sap from plants. They’re related to cicadas and spittlebugs. True to their name, when startled or in need of new feeding grounds, they leap many times their height into the air and find another leaf to feed upon. As members of the order Hemiptera, leafhoppers are “true bugs” – insects with specialised mouthparts that feed by sucking.

Sometimes when you design a game, you want to include things purely to set the tone and enrich the world. That’s the case for leafhoppers in Empires of the Undergrowth – they’ll appear in the leafcutter levels to bring a sense of biodiversity to our recreation of the incredibly varied rainforests of Ecuador. The leafcutters obviously do not eat other insects, but their leaf-cutting activities will disturb the leafhoppers!







One of our developers John took a few minutes to make this post on our official forums during the last week. He details some commits (changes) made to the game source control by himself, Liam and Matt over the course of the Christmas break. Please follow that link and have a look through it yourself, but I thought I’d just highlight a couple of points he included for the sake of intrigue:

• Balance changes to the refuse chambers – in this commit John is referring to a mechanic that will be introduced with the leafcutter levels, the refuse chambers. Leafcutters grow fungus from their foliage cuttings, and the spent fungus produces waste. It will be the job of minim workers to remove waste from the fungus gardens to the refuse chambers. Failure to have sufficient refuse chambers far enough away from the gardens will have a detrimental effect on the workforce.
  
  
• Focus on large creature patrols – we’ve shown you some fairly big new beasts for the leafcutter levels, but we’ve not shown you everything! There are some things we don’t want to spoil just yet, if at all.
  

The Spiny Devil - one of the creatures getting several size variations

• Medium-sized Spiny Devil – like the beach tiger beetles, hermit crabs and wolf spiders in the 2nd tier, several of the rainforest critters will come in several sizes. This includes the spiny devil, praying mantis and harvestman. See the previous newsletter for details on some of those beasties.
  
  
• Leafcutter resource system – resource complexity has a step up with the leafcutters, as a natural increase in complexity makes sense from a gameplay perspective. These things need careful implementation and balancing – and that’s an ongoing process.
  
  
• Leafhoppers and a system to manage them – as well as doing the artwork for our decorative leafhoppers (detailed above) Matt has created a system to handle their behaviour. The other denizens of the rainforest won’t interact directly with the leafhoppers (they jump away much too quick) but they’ll still realistically ping themselves away when approached.
  

Leafhoppers doing leafhopper stuff

John hopes to continue these sort of posts on an informal basis every so often – just to give a little insight into the day-to-day work that goes into the making of Empires of the Undergrowth. He’ll only be posting them on our own forums, so this is a good time to get yourselves signed up to them and introduce yourselves to our small but friendly community.



We’re getting lots of people (quite rightly) asking how far away the leafcutter update is. We’d like to think that we can recognise things we’re not very good at, and it’s fair to say that estimating our release dates is one of those things. In our experience a missed deadline, even a vague and non-specific one like “winter”, is likely to cause disappointment in our fans and that’s the last thing we want.

The leafcutter levels (3.1, 3.2 and Formicarium Challenge 3) are each an order of magnitude more complex than anything and everything we did in the 1st and 2nd tiers, and it shows in our current testing. Rest assured, although we are taking our time, we are taking our time to do it right and the results will be worth the extra patience you lovely bunch have shown yourselves to have in abundance.

It’s been policy for a while, but to make things explicit – going forward we won’t be giving vague guesstimates – only solid dates when we’re sure of our ability to meet them.



As ever, we love trawling through the screenshots on Steam to find the best of the uploads. Take your screenshots on Steam (F12 by default) and upload them once you quit the game. Photo Mode (F9) will help you get some pleasing angles on your snaps! If you’d prefer not to deal with Steam, you can also email your pictures to [email protected].

An easy-on-the-eye Formica fusca colony from MorPacke

In this patch we have hunted down a bug that is crashing the game on Queen of the Hill. We thought we had it solved in the last patch but people were still reporting it. Thanks to our great community we have finally found it and interestingly it was to do with the ramp and ants falling through them when the tide rises. We have now changed how these work.

• Fixed an issue crashing Queen of the Hill on certain hardware setups under certain circumstances. This issue was caused by ramps being made pass through-able when the tide rose on 2.1 and 2.2. This would occasionally cause ants that were pathing on them to fall and potentially re-path in a near infinite loop. This bug has been hard to replicate and hence hard to fix but special thanks to our community for helping us locate this one. Due to this we have made changes to how this works.
  
• Fixed issues with creatures picking up other creatures (Interpolation should work vertically, creatures should correctly stick to the mouth and animation should play correctly during pickup)
  
• Fixed an issue in Freeplay telling the player waves would spawn consecutively after 8 minutes when it should have been 12
  
• Fixed a message telling the player waves would come every 5 minutes when in reality it is 6 (if you include the timer countdown)
  
• Clicking the door in the lab no longer closes the game
  
• Fixed an issue in Freeplay where the warning timer was not using the same calculation as the wave timer
  
• All values in ant improvements are now rounded to 2 decimal places
  
• Freeplay wave timer info now accurately represents the time between wave spawns and not the time from one wave spawning to the start of the next timer starting (13m setup 6m between)
  
• Fixed some issues with the size of woodworm food items
  
• Key presses that are meant to switch from above to below ground have been disabled in photo mode to prevent strange lighting changes
  
• Fixed an issue where food could get stuck on the surface in your ant tunnel
  
• Notification about the Gate mission 1 will no longer appear after you have completed it
  
• Fixed an issue shrinking the areas ant could appear on the surface from the nest area
  
• In-game UI elements are no longer shown in photo mode (Markers, chamber info ect)
  
• Force player out of photo mode and prevent them entering it when victory of defeat is happening
  

• Creatures will no longer pass though ramps as the tide rises falling into the water. Instead any ants assigned to markers touched by the water will be immediately sent home when the marker is dismissed.
  
• Beach tiger beetle larvae have been given high slow resist
  
• On Queen of the Hill Challenge Mode in Easy, Normal and Hard beach tiger beetle larvae will spawn more often and increase the rate of spawns each day
  
• Dead creature harvest locations and pickup locations have been more centralised, meaning ants should no longer carry woodworms within their bodies (at least less often) and harvesting should be from a more logical point of the dead creature
  

A hotfix was released for this patch on 10th January, bringing this update to version 0.1353

• Fixed an issue with ants staying with and repeatedly dropping a food item when all food storage was reserved, but not all food storage full
  
• Uber creature resistances have been lowered
  

We've pushed a hotfix update to Empires of the Undergrowth to fix 2 major glitches.

• Fixed an oversight with the music switch over from day to night that was crashing 2.2 Queen Of The Hill for some players
  
  This issue was missed by internal testing since it only seems to happen on certain hardware configurations and only for a small minority of players.
  
  
• Fixed an issue that was giving players 20 territory each time they returned to the formicarium
  
  An oversight in territory given to players on the upcoming 3rd tier Formicarium missions made its way into the previous build, creating an infinite territory glitch.
  
  

With the exception of a few necessary balance changes and fixes for the more recent playable builds, the team’s sole focus for the past month has been the leafcutter update. Over the past few weeks we’ve been showing off some of the progress on the creatures of Ecuadorian jungle where these levels are based. Our artist Matt has been producing amazing work to bring this sublimely rich ecosystem to life within Empires of the Undergrowth. John and Liam have been working on bringing the creatures into the game and figuring out how they interact with our leafcutters. This newsletter will therefore focus mainly on the amazing biodiversity of the rainforest setting. Without further ado, let’s get to having a look at some of these fantastic beasties!

The rainforest at night

Rove Beetles

Rove beetles are a diverse group of insects that can be found the world over - in fact, the European devil’s coach horse that’s already in the game is a kind of rove beetle. The main distinguishing feature for these beetles is the short elytra (wing coverings) that leave most of their backs exposed. Many, many species of rove beetle exist, and some of them are rainforest dwellers. They’ll come into conflict with our leafcutter ants.

Rove beetle larvae

Although leafcutters do not eat other creatures, they are fully aware that other creatures will happily eat them - and so they’ll defend themselves with the same deadly zeal that any self-respecting ant with giant slicing jaws would.

Two varieties of rove beetle adult

Spiny Devil Bush Cricket

The fearsome spiny devil bush cricket (Panacanthus varius) faces off against a leafcutter colony. Covered in defensive spines, this monster may well be guarding some of the choicest leaves for the harvest - which means it must be confronted. Bush crickets are also sometimes known as katydids.

https://youtu.be/H6ODtEzI4gs

In-game, the spiny devil's spines will mean that any creature that does damage to it will suffer some damage in return, whether or not it is actually being attacked by the cricket. It also has an area of effect bleed attack which will continue damaging the target for a time after.

The spiny devil is not idly named!

Praying Mantis

The mantids are an iconic group of insects - known for their "praying" folded forelegs and upright posture, as well as their covert hunting techniques. This particular species is a leaf-mimic praying mantis (Pseudoxyops perpulchra), specifically adapted to hide in the foliage with near-perfect leaf camouflage. In its final instar it's a voracious hunter of insects, using its natural stealth to get close to its quarry.



The leaf-mimic mantis will have a unique stealth ability reflecting its natural prowess at ambush attacks. It will not appear on the minimap - nor will its health bar be visible - until it decides to engage the player. The range at which ants can notice and attack it is also much lower than it is for more conspicuous creatures.

Army Ants

The relentless march of the army ants is legendary. These ants form large colonies, living a nomadic lifestyle. They scour the rainforest, sending out waves of workers to demolish anything in their path to feed their expanding empire. Like many species of ant, they have a distinct caste system. In these pictures we see two separate castes of Eciton burchellii - small and medium-sized workers.



Featured below is the soldier caste - analogous to the large majors that the leafcutter colonies produce. These brutes protect the flanks of the army’s trails from attack. Their large mandibles are more than capable of delivering a killing blow to any number of arthropods and a painful nip to things larger. Unless prepared for battle, it would be advisable for the denizens of the rainforest undergrowth to avoid the trails of the army ants lest they incur the wrath of their imposing protectors.



In Empires of the Undergrowth, the leafcutter colony will encounter army ants overlapping its territory. They represent a strong existential threat - unlike our leafcutters army ants readily eat meat, and the brood of a fledgling leafcutter colony would be a nutritious prize.

One Year On

As of 1st December 2018, it’s been one year since we released the early access version of Empires of the Undergrowth to you all. We’ve had incredible support, love and kindness from all of you and that makes each day we work on the project a joy. Such an ambitious project is not without its difficulties and pitfalls, particularly for such a small team, but with you guys behind us we feel we can achieve everything we’ve set out to do.

The last year has seen some big changes to not just the game, but the lives of those of us on the team. All three of the developers have been able to give up their day jobs to work exclusively on the game. Our entire lives have been restructured around it and that’s a very exciting thing.

As far as the game itself goes, we’re not too far from a huge update in the form of the leafcutter levels. We know you’re all desperate to sink your jaws into them, and we can’t wait to get them out to you. There are still some more surprises in store for this update, and we’ll be teasing a few more of them as we complete the work. Keep an eye on our social media - particularly Facebook and Twitter - for those.

So, here’s to the future! And here’s to you all, you lovely bunch. Continue being awesome.

YouTuber Highlight - Flexible Games

Flexible Games has been playing Empires of the Undergrowth diligently for several weeks now. What’s made his playthrough fun to watch for us as developers is that he’s gone into the game blind, with very little knowledge of what’s in store. Genuine reactions like this are often hard to come by, and it’s been an experience watching him get to grips with the systems. Here’s part 1 of the extensive series - he’s now completed the current campaign levels and moved on to Freeplay.
