Fire Ant Update Coming July 27th - Trailer

We are delighted to announce that the fire ant update is coming on July 27th 2022! Grab an eyeful of the updated trailer that shows off the new environment and (some of) the new enemies that come along with it.

[previewyoutube][/previewyoutube]

A whole new formicarium tier awaits - guide a young fire ant (Solenopsis invicta) queen and her first brood as she invades an unfamiliar swamp environment in two full new story missions. The swamp is swimming with amphibians that are not adverse to a spicy snack!

As well as having by far the most critters we’ve added in a single update, the 4th tier includes a long-awaited class of enemy: titans. Titans are huge creatures - big enough, in fact, to be climbed. They do not represent an existential threat since they’re too big to invade the nest, but they must be dealt with in other ways and are a challenging obstacle to be overcome.

Fire ants themselves have a unique ability, outside of their incessant stinging - by linking their bodies together, they can form floating pontoons that can cross water, reaching resources previously unplundered. This is a skill that will come in exceptionally handy in the regularly-flooded green swamp.

They come in two very different soldier varieties - pervasive and vigorous. If you choose pervasive, they will spawn for free after the egg has been on the tile for a time. This can be a crucial advantage when food is scarce. Alternatively, vigorous fire ants will have a significant buff to stats for a time after birth. This opens up the potential for aggressive expansion, but beware of pushing too far too fast. At level 3, both variants will be able to spawn 2 ants from each tile.

Once you’ve conquered the swamp, return to the formicarium where the scientist is far from done with you yet - what dastardly design has he decided is due to your Formica ereptor colony?

Finally, welcome to new people who are finding us through the Steam Summer Sale! We hope you find our little ant game worth your attention, and if you’re considering giving it a go you’ve joined us at a very good time.

We’ll see you on July 27th for the invasion of the fire ants!

March 2022 Newsletter

This will be a shorter-than-usual newsletter, just catching up with the last of the things we’ve posted on our social media before the fire ant update. We’re rounding the corner to the home stretch on that front now, and whilst we’re not quite ready to announce a date (that will come out of the blue one day with a trailer) we are at a point where we don’t want to spoil anything else, as we still want there to be plenty of surprises for when the update drops.

We’ll go over a few things that have been previously announced – all of the things shown in this newsletter are from the 4.x missions.

Environment Showcase


Our environments for the fire ant update are near complete, and we put together this short video to highlight some of the artwork by our dedicated environment artist, Dan C. Level 4.1 will be called “Cold Blood”, and this is the arena in which it is set. The swampland has poor soil so many of the plants here have evolved to be carnivorous.

Venus Flytrap in Action


One such carnivorous plant is the iconic Venus flytrap. The leaves are tipped with traps that exude nectar, attracting ants and flies. Trigger hairs on the inside of the trap cause it to snap shut when touched, effectively turning the traps into stomachs which then digest the prey. The flytrap will act as an “area denial” obstacle – ants will climb it but will inevitably trigger the traps, before re-opening after a cooldown.

Caterpillars & Sweetbay Magnolia


Caterpillars have recently hatched on this young sweetbay magnolia sapling. Such an infestation may well be fatal, but help is at hand – the resident fire ants are very glad of the extra protein. Caterpillar-spawning plants will provide a rich food source for your fire ants, as long as you can survive the competition required to keep the supply lines open.

Milkweed & Aphids


Milkweed plants are often homes to sap-sucking aphids. The aphids excrete a sweet substance called honeydew, which fire ants find irresistable. The ants will care for their aphid flocks, protecting them from predators, jealously guarding them from competing colonies and even moving them to safer locations.

Screenshot Central


Let’s close out this shorter-than-usual newsletter with the traditional Screenshot Central post! The easiest way to get these to us is to post on the #screenshots channel of our Discord – I usually have a look through it once a week or so for great snaps for social media and the newsletters.

0.2331 Released - Controller Support, New Language Localisations

The main feature this time is full support for gamepads (Steam Deck, XBox One and PlayStation 4 controllers are all officially supported). If you prefer to play with a gamepad or would like to try it out, now is the time! We are also adding six new languages localisations (we are not updating our store page to say we officially support these yet; they should be considered to be in beta for now). The languages are Czech, French, Japanese, Korean, Dutch & Polish.

There’s also some fixes and changes, detailed below, including a fix for Mac so Mac users should be able to play Hibernation now! We have also moved the game files to an encrypted form, so the download is likely to be larger than a regular patch since Steam won’t recognise the encrypted files.

Headline Features


  • Gamepad support added
    • All standard gamepad buttons now have functions which can be viewed from the options menu
    • When using a gamepad, key bindings show gamepad glyphs
    • Several notifications have been added or replaced to explain gamepad support when using them
    • The Hungry Spider can now be properly controlled with a gamepad
    • XBox One, PlayStation 4 and Steam Deck gamepads can be selected from the options menu to display the correct glyphs
    • When using Big Picture mode on Steam, or the Steam Deck the on-screen keyboard will display when needed
  • Several new localisation languages added for testing (Czech, French, Japanese, Korean, Dutch, Polish)


Other Fixes & Changes


  • Mac build is now updated to include the Hibernation extra level
  • Fixed a memory leak in creature despawning
  • Fixed some minor pathing bugs
  • Several areas in the game with small text have had their text size increased
  • Fixed an issue where the mouse pointer would not change until moved in some circumstances
  • Fixed an issue where brood chamber hover information would come up overground after having it come up underground
  • Fixed an issue where ants could get stuck on the overground nest exit
  • Fixed an issue where sometimes level setups could drop off the screen at the bottom
  • Minimap pings will now display more consistently
  • Fixed an issue where dragging the mouse during a cutscene could cause tiles to tag for digging
  • Fixed an issue where tiles would be left highlighted when tabbing to surface
  • Fixed an issue where dead creatures could sometimes be carried off to the side of the carrying ant
  • Fixed an issue where the mouse cursor would change when hovering over an enemy nest but not change back when moving off it
  • Added in quick build / upgrade key binding (default to thumb mouse button 1). Hold to automatically select the upgrade or build tool most suitable for where your cursor is

January 2022 Newsletter

Welcome to the year of the fire ant! For those of you wondering how we’re doing with the 4th / fire ant tier, we’ve recently gotten the last of the dialogue and voice acting into the game, and sent things off to translators for localisation. Keep an eye on our social media for further public narrowing of our release window. As always we won’t give a date until we’re certain we can hit it. The marketing team have indeed been working on the trailer as the art team completes the detailing on the levels, and we’re positively itching to show it all off to you – but we have to be patient too.

The Year of the Fire Ant is upon us!

Let’s talk about a few things that have come up over the last couple of months, including the exciting return of a creature long thought lost to the sands of time – the velvet worm.

The Velvet Worm


Velvet worms were cut from the 3rd tier for time, since they used what was at the time a unique animation system for its trailing behind, which was not finished. Since two 4th tier creatures use this (the eastern newt and the dwarf salamander), we’ve been finishing and refining that system and we feel that once we’ve done with the 4th tier it would be a shame not to bring the velvet worm back into the fold.

[previewyoutube][/previewyoutube]

Widespread in tropical South America, velvet worms are voracious, soft-bodied hunters with a special weapon they use to incapacitate their prey. When hunting, they use two specialised slime glands that are either side of the mouth, trapping the target in a sticky web of mucilage. This makes catching and consuming it significantly easier. In nature, it can also use this slime defensively, wriggling free of potential predators.

Two sizes of velvet worm

Like many of the game’s creatures, the velvet worm comes in different sizes, from a juvenile to an adult of 7cm in length, which makes it one of the Undergrowth’s larger denizens. We’ll be reintroducing the velvet worm to the 3.x levels at some point, as well as giving it an appearance in an upcoming extra level called Adventure. Both of these are likely to happen post-4th tier, since right now our focus is to get that complete and out to everyone.

Pitcher Plants


Our environment artist Dan C continues to produce amazing swamp-related items for us, and one of his latest creations is the pitcher plant – the second carnivorous plant of the 4th tier. This swamp-dwelling flora has specialised leaves that grow into a jug shape, which it fills with digestive enzymes. The rim of the plant is slippery, making it a treacherous surface for insects to be scaling.

As pretty as a pitcher

The plant attracts victims with enticing scents and sweet nectar – and there is a chance that a fire ant may escape with a prize, but the possibility of an unfortunate death is always present – and in more ways than one. This pitcher is the favoured lurking spot of the green lynx spider, and it’s always ready for an easy meal.

Sorry, arachnophobes 🙁

The Gaster Flag


One of the peripheral species that will appear in the 4th tier is the little black ant, Monomorium minimum. They will be the smallest ants in the game – even the diminutive fire ants will look big besides them! To even the odds, they have a chemical and visual threat known as “gaster flagging” which will cause a debuff to enemy units caught in it, and they will not use it sparingly. The video below shows them attacking a group of fire ants – note the debuff symbols over the fire ant victim’s heads.

Steam Deck


We were lucky enough to be sent a little present from Valve a couple of weeks ago, a Steam Deck developer kit. We’ve been testing all of the games we publish on it, and Empires of the Undergrowth runs exceptionally well without us having to make any modifications to the game when using Valve’s Proton system (software which allows a Windows program to run natively on a Linux operating system, like SteamOS that the Deck uses). This is a remarkable achievement for a hand-held PC equivalent, and it’s clear that Valve has made an exceptionally desirable product here.

[previewyoutube][/previewyoutube]

There are things we’re working on to make the experience even better, such as including Valve’s controller glyphs, having a proper keyboard in the UI and creating an official control scheme. These will eventually get us the coveted “Verified” tick, but we’re not sure exactly when that will happen right now. Rest assured, the game works very well right now via Proton, and with some small tweaks and changes coming at some point in the future it will work fantastically.

Testing on the Steam Deck has opened us up to some of the shortcomings that the Linux build of the game has, and it is very clear that the best way to play Empires of the Undergrowth on Linux is through Proton as things currently stand. We’ll talk more about this over the next few weeks.

Freeplay Balance


There has been some discussion on the forums (both the Steam ones and our official ones) about freeplay balance. In truth, freeplay is not in an excellent spot right now, since we’ve been focussing our attention elsewhere. This problem is likely to be compounded as we add more creatures and mechanics from the campaign into it.

There are a few reasons for us waiting to make any major changes to freeplay, and the most obvious one is that we’ve been working almost exclusively on the 4th tier for some time now (with the odd exception of some extra levels here and there, but development time on them is practically nil compared to the campaign. Another reason is that we will be replacing the existing AI in freeplay with a new bot system that has been developed for use in the remainder of the campaign levels. It is significantly smarter than the current implementation, and can more easily be tweaked to play like a player rather than the more rigidly-behaved colonies in the campaign. We hope that it will be possible to make them competitive without having to cheat – we’ll see how we do on that front!

The net result of this is that it would be inefficient for us to put much in the way of time into fixing freeplay as things stand, since our focus will switch to a pretty extensive overhaul of it once fire ants are released. This follows our usual development pattern of major release then interim update focusing on freeplay before the next major release.

In short, we hope to be able to make freeplay a much more balanced and enjoyable experience, but not until we reach the interim update period between the 4th and 5th (final) tier. Until that point, we are aware that things are not exactly right where they should be.

Hibernation


Thanks to everyone who played our winter-themed extra level Hibernation over the festive season! It’ll be sticking around permanently in extra levels, rather than disappearing like the Hungry Spider event levels. It features a unique resource – vegetation – and heating tiles, which must be stocked before the depths of winter arrive. If you haven’t seen it yet, check out the trailer below. The level features custom music and voice acting – a first for an extra level.

[previewyoutube][/previewyoutube]

I just thought I’d clear up a little confusion with this level, since it comes up semi-regularly – you must have the specified stored vegetation in your heating tiles at the moment that the mid-winter hits. This is when the narrator says his “bleak mid-winter” line, and if you’re not at the specified level at that point the queen will inevitably freeze. So, that’s the targeted time you need to be aiming for!
