Xenonauts 2 News

Hello everyone - time for our development update for March. Apologies for this being a few days late - the intention was to time the update to coincide with the release of V23 but we've found a couple of crashes which have pushed the release back. For those interested, we'll be releasing V23 on our Experimental branches at some point this week.

Chris has been focussing on campaign balancing this month, which is always a significant undertaking given a full campaign playthrough is probably 15-20 hours long (i.e. at least two full working days). Each attempted playthrough results in a number of balance changes that need to be made, bugs that need to be fixed, usability changes to be made, gameplay mechanics that need to be checked out because they may not be working properly, etc. This is critical work, but not especially interesting to talk about - we therefore don't have many "big" features to discuss in this update, so here's a general round-up.





The main new change on the strategy layer is an attempt to introduce more strategic pressure. The Orbital Bombardment mechanic has made a return in a somewhat altered form, and it's now effectively a monthly performance target communicated in a slightly more thematic way. We're aware that the community had some concerns about this mechanic in the past, but this new format shouldn't cause any issues.

At the start of the month Orbital Bombardment increases Panic in all regions by a certain amount (e.g. +25 Panic) that increases as the game progresses. If any region has over 100 Panic at the end of the month it surrenders and is lost to the aliens, so the player must try to generate enough Panic reduction during the month to cancel out the Panic gain. Monthly funding from a region is tied to its Panic, so success means funding goes up and failure means funding goes down.

Panic reduction is achieved by defeating the alien invasion - shooting down UFOs and completing ground missions like Terror sites. These generate a local Panic reduction, but also a global reduction. The regions you are protecting best will have the lowest Panic but even undefended regions will have lower Panic if it looks like humanity is winning the war against the aliens.

The gameplay effect of this is much like the monthly funding evaluations that appear in every X-Com game, but it serves to reduce the amount of damage that can be caused if UFOs spawn repeatedly in undefended regions due to simple randomness, and it also ensures that the game ends more quickly if the player was underperforming (it was always a bit silly that it took 3-4 months to lose the game in Xenonauts even if you never shoot down a single UFO or win a tactical mission).



We've spent quite a bit of time this month fixing gameplay issues to do with the Xenonaut Base Defence missions, as we've introduced a base attack on your main facility by the Cleaners to increase early-game mission variety. While this biome still looks a bit ugly (it hasn't had the visual pass yet) the gameplay is more solid.

The first thing was to get the Sentry Guns set up. These cheap and durable vehicles are only used in base defence missions, and they had some display issues that have now been corrected. Also, their LMGs should now be upgraded appropriately as the player progresses down the tech tree.

The second thing was the spawning / deployment phase of the mission, which had apparently got broken at some point in development. The player can now deploy anywhere in their base at the start of the mission except in rooms where aliens have spawned. Additionally, the alien crews are now correctly splitting into assault teams and choosing the correct type of room to spawn in. Most types of aliens spawn into Hangars as normal, but certain other types (e.g. Reapers) are able to spawn in random rooms due to their ability to climb through vents or teleport.



We also spent more time this month on updating various strategic UI elements to our new style, and the updated graphics for the tactical combat UI may well make it into V23 too.

The Air Combat has also had a few more updates to ensure the new formation / deployment system works properly, and we've also set up the autoresolve to allow the player to manually fight the air battle if they don't like the result the autoresolve gives them. This protects players from the situation where the autoresolve unexpectedly destroys all your planes (usually due to low fuel).

The balance here has changed a bit too. There's now four classes of weapons that have different roles: cannons, missiles, torpedoes and energy lances. These have varying ranges, ammo capacities, and damage profiles vs armour and HP. The ability of an interceptor to perform the evasive roll maneuver is now also tied to the weapons they have equipped, so while energy lances are relatively powerful weapons they also make the interceptor carrying them more vulnerable to certain enemy attacks.
Finally, we've been working on the blockouts for the final mission this month too. We won't give too much away but there's a few unique rules on this mission that have required a bit of code work too. Hopefully the final mission will be playable in V24 even if the final art pass on the map probably won't happen until closer to release.

That's it for now - thanks for your patience as we continue working on getting the game into shape.

Hello everyone - it's time for the February update! With this update being a bit early and the last one being a little late, we've only had three weeks since the last dev post but a lot has been done in that time.

Releasing a new public build is our main priority right now and so we're actively working on Build V23.

We've mostly been working on polishing the experience and improving the game balance, and we've spent a lot of time playing the game this month to help facilitate that. We've done a lot of work on the Air Combat, as we've been adding various new features to it recently (such as the pre-battle deployment phase and the different formations that UFOs can spawn in) and we've also had to make some quite fundamental changes to the code in order to fix a persistent bug where missile hits would not always be detected correctly.

Although it's frustrating that this issue sapped away quite a bit of time, having missiles occasionally pass straight through their target without exploding is clearly not acceptable in a game where it can mean the difference between victory and defeat!

There's already been a lot of tweaks to the game balance and we'll continue with these as we work on V23. The early-game Cleaner missions are now a research chain that give you a series of standalone missions which occur alongside the alien invasion rather than before it. We've also done a pass on all the UFO / tactical mission crews to ensure the right aliens are spawning in roughly the right numbers at the right time. There's been a load of updates to the tech tree, sometimes to fix things not unlocking correctly but mostly to ensure a relatively steady flow of research and upgrade projects throughout the game. The tech tree is more extensive than in X1 and this can cause problems in some instances, for example if the player is doing too many research projects between ground missions then it can get a bit overwhelming.

We've also fixed a lot of bugs / issues we've encountered while playing the game, and updated various game systems that weren't working quite right (e.g. the Sentry Guns). We've updated some more of the strategic UI to use the new visual style, various new terrain tiles have been added to the game and we've produced the final destruction states on more terrain objects. Windows have continued to be a pain to get working correctly, but when you play a tactical mission on a finished biome like the Polar biome things are looking and feeling good. It'll be nice when we have all the biomes up to that standard, but it's taking a while to churn through all the assets. We're recruiting a rigger to get our new civilian 3D models into the game, and if all goes well we'll have those in V23 too.

All in all, it's been one of those months where we've fixed far too many things to mention individually but relatively few of them are big headline features you can write about in updates like this.
Once V23 is out, we're planning to focus on a few more mechanics that set the game apart from the first Xenonauts, as we're in quite a nice place with development now where the campaign is largely functional and all the remaining work is adding in new assets, polishing what we have, and adding things to make the game more distinct from its predecessor.

The biggest thing we want to test is various more significant alien abilities that will hopefully make each alien race feel more distinctive. For instance, we're going to test whether it makes combat more interesting if the regenerating Sebillian aliens enter a "downed" state when killed, and have to be finished off within a couple of turns else they'll get back up again. Or whether Wraiths are more interesting if they can enter a "ghost" state after taking damage and take reduced damage until end of turn (although perhaps only from kinetic damage). Basically what we're looking for is abilities that cause the player to think about how they sequence their actions or encourage them to use a wider selection of equipment than they otherwise would.

That's it for this time - we're hoping to put out the first incarnation of V23 at some point during the week after next (w/c 7th March).

Greetings and apologies for the slight lateness of this update - the team wanted to finish a few things before putting it up.



It's worth discussing why a public build hasn't been released to backers recently. We've been working on a couple of big systems that required a significant campaign rebalance once implemented, as well as some systems that required UI updates. We've also been working on the Cleaner missions that happen right at the start of the game. Anything we put out before that work was finished would have been almost unplayable.

Hopefully the next public build will be coming in about two weeks but will likely need several iterations on the Experimental branch before it represents a better gameplay experience than the most recent V22 build.



The first big change we've been working on is the Armour system. For simplicity, we've now unified the way armour is handled in both the tactical and air combat so Armour is a flat reduction on incoming damage (e.g. 30 damage hitting a target with 10 Armour does 20 damage).

However, there's a wider variety of armour penetration and armour destruction on the various weapons in the tactical combat compared to the first Xenonauts, so the player is now presented with more decisions about the best order to use their attacks. We've added a new grenade that inflicts limited damage on units but is excellent at removing terrain and shredding armour, and we'll be experimenting with armour-piercing ammo for ballistic / Gauss weapons this month too.



We've done another balancing pass on air combat, as we've added a new type of weapon - the energy lance.

Previously this weapon type lacked any real individual identity and part of the rationale for the armour changes was to give all four types of weapon their own niche:

Cannons are short-range, high DPS (damage per second) weapons with 40 ammo. They do low damage per shot so armour reduces their damage significantly, but they also shred armour relatively quickly. Cannons will kill most things but require you to get in close and stay there, which can be very dangerous against UFOs with powerful weapons.

Missiles are long-range, high damage weapons, but only have 4 ammo. They do excellent burst damage so are great at destroying unarmoured UFOs (e.g. Fighter UFOs) before they can attack you, and can also quickly kill other types of UFO if another weapon is used to strip the armour off them first.

Torpedoes are long-range weapons with excellent armour destruction, but only have 2 ammo and are slow and easily avoided by agile UFOs. Hitting an armoured UFO with torpedos will quickly strip away its armour and leave it vulnerable to other types of weapon.
Energy lances are medium range weapons with medium DPS and good armour destruction, and 15 shots. They act somewhat like torpedoes, but trade a shorter range and a slower rate of fire for more ammunition, more versatility, and the ability to hit agile UFOs.

In addition to this, there's been two other major changes to the air combat. Firstly, there is now a "deployment phase" at the start of the air combat where you can set your interceptors up anywhere around the edge of the map, allowing you to group them together or split them and approach the UFO from multiple sides. The type of tactics you want to use are likely to vary based on the type of UFO and the fire arcs of its weapons (and whether it has weapons capable of attacking multiple interceptors at once). You don't get to deploy freely if UFOs on an air superiority mission attack you, however!

Secondly, we've reverted the change where interceptors are always built in squadrons of three. We're back to the original system where aircraft are built individually, and our new approach to balancing the air combat is that UFOs gain some additional HP and Armour for each additional interceptor taking part in the battle. It's still advantageous to send more interceptors into battle against a UFO, but this just gives the player more flexibility in their approach - a single well-equipped advanced interceptor can often now be just as effective as a full squadron of three more primitive interceptors (the latter was almost always better in X1). The convenient lore explanation for this is larger squadrons are more easily detected as they approach the UFO, giving it more time to power up its emergency shielding and prepare for combat. While this may not be entirely "realistic", we feel the gameplay benefits are worth it.



The other significant new mechanic has been the introduction of the tactical combat morale system. This is a similar system to the first Xenonauts but has a few improvements to make it easier to understand and interact with, and hopefully to make the alien psionic abilities feel less random. There's also now a "Focus Mind" button that allows a soldier to spend TU in order to boost their morale, which gives the player a way to defend themselves against potential morale events or psionic attacks if they want.



The problem here is that our current tactical UI design has been straining under the weight of all the new mechanics and UI elements we've added since we implemented it 2-3 years ago, and having to add Armour / Morale bars and this new Focus Mind button has been the final straw. We've therefore been working on the final tactical combat UI design that brings the visuals up to final quality and properly integrates all the new stuff. This is a massive job because it's one of the most important and complex UI elements in the game, but we think we've found a layout that works well - it displays more information than the current UI does and uses less space to do it!



In other news, the Cleaner missions at the start of the game are now a pre-set sequence of four missions with some unique mission objectives to mix things up a bit (as opposed to randomly generated missions that filled a meter that eventually revealed the Cleaner base) a few more screens have had a UI facelift, a few more 3D civilian models and alien armour models have been created and are waiting to be rigged, and we've created some stone ruins to add a bit of variety to our jungle maps.

So, a very busy time for the team and thanks once again for sticking with us.

Happy New Year and all that! Here's a quick update from the Goldhawk team on work that took place in December - this was a slightly short month owing to team holidays but we're back and on track now.



The main focus of recent work has been the soldier Morale system which causes soldiers to panic when things go horribly wrong on a mission. We actually planned not to include this in Xenonauts 2 for quite a while, but ultimately we felt the game would be weaker without it and not having it gives us fewer tools when it comes to designing the alien abilities (particularly psionic ones). This system is mostly now implemented but there's still quite a few bugs and edge cases we're working through.

We've made a few improvements relative to the first Xenonauts. The first is that Morale always starts at 100 for every soldier, and the Bravery of a soldier (boosted by the squad commander bonus) reduces the amount of Morale damage taken when something bad happens (a soldier with 0 Bravery takes about 3x the morale damage that soldier with 100 Bravery does). There's now a button that allows you to spend TU in order to gain Morale, and the morale system is a bit more sensible in general. Units are generally only vulnerable to panic if Xenonaut soldiers are dying around them (particularly high-ranking ones) or the unit itself has been wounded, or if there are psionic aliens messing with their heads.

Balancing is still required but overall it should be a little smoother and easier to understand than it was in Xenonauts 1.



Work on the updated UI designs and final art assets also continues. We've done an updated layout for the tactical combat UI due to the fact that we added several new features since our current design was done, including the Morale system which now needs to be displayed somewhere.

Our UI artist is working on styling that at the moment, and in the meantime we've finished styling several more of the strategy panels. Work on the 3d models for the human civilians and alien armour variants also continues.

As November draws to a close it's once again time for our monthly update. This month we've mostly been working on turning the experimental builds of V22 into something ready to be released on our main Steam / GOG branches. This has involved a total of 6 hotfixes, which might be a record for us!

New Builds

Anyway, V22 is now out. This is the first major update on our main branches since March (apologies for that) and we think anyone who hasn't been playing on the Experimental branches is in for quite a treat given how much the game has changed since then.

The reception to the V22 Experimental builds overall has been very positive, both in terms of comments and the pattern of play that we're seeing from users. Part of the reason that we released so many hotfixes for V22 was that many of our testers have been playing much further through their campaigns than previously, so they're encountering bugs in areas of the game towards the end that haven't yet been tested (or balanced) properly. A couple of the late-game UFOs had broken teleporters that meant you couldn't actually complete those missions, for example. It's very encouraging to see that people are already able to spend 5+ hours playing a campaign, when we as developers know we've still got a lot of improvements left to make.

Content Additions

There haven't been too many new features added this month, unfortunately: the coders have been busy fixing bugs and Chris has been off for a couple of weeks on paternity leave, so there's not been too much time. Nonetheless, a few pieces of new content have arrived - a couple more research projects have been written up, some new terrain tiles have been added and more destruction states set up on existing tiles, various corpse art for the aliens has been done, and a little bit of new UI art has arrived.

We've done quite a bit of work on 3D characters this month too. Now the Xenonaut models are complete, we're working on the final high-quality 3D models for the local civilians in each map. This is quite a big job as there's probably about 30 different clothing items that need to be modelled and combined in different ways to give us all the variants we need to have realistic-looking locals across the many different biomes in our game, but the progress so far is looking good.

We're also starting to work on the rank / armour variants for various aliens, which we want to look a little more distinctive than they did in Xenonauts 1. We've now finished the Psyons and will be moving onto the Sebillians next.

Spacebar Speedup

The one new code feature we spent some time on this month was trying to make controlling multiple soldiers easier during tactical combat. We've done this by setting up the spacebar to accelerate unit movement - pressing space while a unit is moving causes them to finish their move pretty much instantaneously. Pressing space when a unit isn't moving causes the game to mark that soldier as having finished their turn and automatically select the next nearest soldier that hasn't finished their turn (of course, you can re-select "finished" soldiers manually if you want). Once all the soldiers have been marked as finished, space will end the turn. You can now play through a turn relatively quickly if you want, which can often be useful towards the end of a mission.

With December including the Christmas holidays we'll be having another truncated month, but with V22 done we are hoping we can get some cool new features in for testers in January.
