I hope everyone had a happy Easter, and I figured that I should probably post something up to explain what we've been working on lately with regards to Xenonauts 2 given the unveiling of the game has not yet happened.
That unveiling may be a little further away than we thought thanks to a few snags coming up with the promotional art. The most obvious of these centers around the design of the UFOs, which we haven't yet finalised. The artist who was working on them (the UFO artist from Xenonauts 1) has had to drop out because of the demands of his full-time role, and the work was already proving more difficult than we expected.
What we want to avoid is a repeat of the UFO problems we had in X1, where we designed some cool-looking UFOs and then found putting them in the ground combat missions to be a rather painful experience. This negatively affected the gameplay too, as it forced us to make the UFO hulls indestructible (reducing tactical possibilities) and it led to situations where players found tiles around the edge of UFO hulls to be unexpectedly blocked for line of sight / fire purposes when the tile grid failed to cope with the curve of the hulls.
We're therefore making sure we get things right with the UFO designs this time, but this is awkward from an art perspective because the "main promo image" (the X2 equivalent of the "command room" image from X1) features a captured UFO in an underground Xenonaut hangar, surrounded by the various Xenonaut staff etc. It's going to be a really cool image and the captured UFO is a major plot point ... but if we're not 100% certain what the UFOs will look like yet, it's a bit difficult to finish it.
The other art issue is that of in-game screenshots; we're not yet in a position where we can show off high-quality in-game art assets. To be honest, Xenonauts only started looking presentable about 50-60% of the way through development and the real polishing didn't come in until it was 80-90% done. Xenonauts 2 has some way to go before we're at that stage, particularly because now we're working in 3D it takes more effort to make even good-quality art assets look good (in a 2D game you just stick the pretty art in the game and that's that, but in 3D you need to make sure all the materials, lighting and render settings are all done right to get maximum effect.)
So that's the bad news; we need to at least finalise the UFO design language before we can properly announce the game ... so now I'll try to give you some good news to counter-balance that. We are obviously still working on the art despite that, and we're developing a more realistic and cohesive style for the Xenonauts and their world than before. As an example, here's the rough concepts for the Xenonaut uniforms for X2.

From the left, the characters are: you (head of the Military Division), the Chief Scientist (head of the Science Division), Operations (head of the Politics & Operations Division), and a (unnamed) Xenonaut soldier. We've tried to make the soldier look a bit more modern than before; the basic uniform was pretty lame in X1 but this retains the essence of the original design whilst also looking a bit more believably military. The other three characters have been designed and coloured so the three divisions of the Xenonauts look distinct from one another, but clearly all belong to the same organisation. I think the dark grey also looks more "secret organisation" than the designs from the first game.
We've added a new character to the game for plot reasons, but also because I want there to be another voice in the game other than the Chief Scientist - I want to keep his personality the same as it was in the first game, but I'm concerned the joke will get a bit old if he's the only person talking to you in both games. Splitting the Xenonauts into three divisions doesn't have any gameplay effect, but it should help us add a bit more character to the world and help with the storytelling; your character is very much the junior member of the trio at the start of the game.
Also, I finally bit the bullet about a month ago and learned how to code so I could properly prototype the Xenonauts 2 strategy layer. I implemented most of the strategic game in Excel / Visual Basic, using an auto-resolve system for the air combat and ground combat missions. A bit of experimentation allowed me to figure out which of my ideas for the strategy layer was the most fun, and I'm confident that the one I settled on is going to work for us - even playing the spreadsheet version of it is quite enjoyable!
I imagine most of you will be pleased to know that we think we've found a way to integrate the Xenonaut ground missions into a wider strategic struggle; the final design incorporates elements from a number of the different strategic designs I've raised on the forums in the past and even some elements from our previous concept Pathfinders. In the absence of pretty pictures, I'll give you a bit of information on what we're planning:
Strategy Design:
Defensive Perimeters: The basic idea is that humanity has five "defensive perimeters" against the aliens, with the most remote and least important regions of the planet being the first perimeter and the Soviet / NATO heartlands being the final fifth perimeter. There's no longer any concept of regional funding etc; you lose the game when the final defensive line falls to the aliens (although there may be some kind of super-hard mission that appears if you fall *too* far behind, either getting you back in the game or ending it immediately).
A defensive perimeter contains Infantry units, Armoured units and Interceptor squadrons. Infantry units are the most numerous and soak up most of the damage from alien attacks; if an alien unit attacks your defensive perimeter it will generally kill several units of Infantry before being destroyed (the effectiveness and survivability of Infantry depends greatly on how advanced their gear is). Armoured units are few in number but act as a counter to armoured aliens like Androns; you will automatically lose an Armoured unit to counter a unit of attacking Androns if one is available (if not, expect to lose a LOT of Infantry).
The Interceptors are the planes you control in each region. You use these to counter alien UFO activity in the perimeter, but they are a precious and non-replenishable resource (and attacking a UFO *is* going to cost you a number of planes). However, the key thing here is that the only reliable way to capture most technology for research is through shooting down UFOs and doing the crash site mission - and the UFOs bombing your defensive lines are not necessarily the juiciest targets for this. You've got a limited number of planes and you need to balance protecting your territory against shooting down the UFOs that offer the best potential research rewards.
Event Timeline: The Event Timeline displays all the alien events occurring in the next ten turns / Geoscape days. The Xenonauts start with only limited visibility of the Timeline (e.g. only three days of warning for each attack) but investing in improved intelligence / code-cracking will allow the player to see further into the future.
The Timeline is split into aerial and ground sections, and alien units spawn at Day +10 and work their way towards the player one turn at a time. If they have not been dealt with by the end of Day +1, they will attack the current defensive line and reduce the number of defenders. To prevent this, the player is able to attack any visible alien unit on the Timeline with their Xenonaut soldiers / interceptors. Successfully winning the mission removes the alien unit from the Timeline entirely, and if a defensive perimeter falls then the entire Timeline is cleared and recalculated.
The player can launch one ground mission and one air mission each turn, but in practice the soldier fatigue system and the limited number of interceptors means that this cannot be sustained for long. What actually happens is the player has to makes choices about what rate of attrition is acceptable for their defensive line, and pick off any alien units that look too strategically threatening by running a ground mission against them.
Obviously, this is made more complex because the aliens all have different abilities and some are far more dangerous than others at any given time. For example, in the current draft:
- Alien "thralls" have no special abilities, so generally are not worth wasting time on
- Psyons (aka Caesans) gain +1 ATK for every Infantry unit in the defensive line, so are extremely dangerous early on
- Harridans kill a single Infantry unit every turn, but take no damage in return. Never the most urgent threat but can accumulate a lot of kills if left alone too long!
- Androns are harmless if you have an Armoured unit available to deal with them, but are extremely powerful otherwise
- Wraiths will raid your Interceptors or Armoured units and destroy a unit of them if you have any left in the defensive perimeter, if not they will take on your Infantry (which they are much less strong at)
Therefore the strategic calculation is always changing. Letting a unit of Wraiths destroy a full squadron of five Interceptors would almost certainly be a mini-disaster for the Xenonauts and in that situation the player would probably want to intervene to take them out before that happened ... but if there was only one or two planes left in that squadron, it might not be worth protecting them. But in that case, you'd have to keep your air force grounded until the Wraiths had come and gone - after all, if you lose a couple of planes on the next mission, those Wraiths are suddenly targeting a full squadron of five Interceptors again, etc.
Similarly, if you can see from the timeline that a defensive line is about to fall but there's only one alien unit marching towards it in the next three or four days, it might be worth doing even a tough ground combat mission in order to win a few more days of "free" research before the aliens overrun the territory.
Proliferation & Resistance: One of the key mechanics in this system is proliferation of newly discovered alien technology from the Xenonauts to the rest of the world. Doing this brings major benefits; firstly the Xenonauts get access to an unlimited quantity of the proliferated technology (e.g. laser weapons), and secondly it improves the stats of all of the Infantry Units holding the remaining defensive perimeters ... effectively slowing down the alien invasion and buying you extra time to complete the game. We're not sure yet if you'll get controllable local forces backing you up on ground combat missions supporting the defensive perimeter, but if you do then they will also only have access to proliferated technology (so will be much more useful if you've proliferated them some good gear).
Sounds pretty useful, right? Unfortunately, the aliens gain increasing resistance to your newly-developed technology the more it is used against them. Tech that is not proliferated will stay effective for much longer against the alien forces (particularly if you use it sparingly), whereas the aliens will quickly build up a resistance to tech being used against them on a global scale. Coupled with the fact you can further improve and develop tech once it has been researched (e.g. Laser Weapons V2, Laser Weapons V3, etc), the choice of which tech to research next and whether you should proliferate it should be much more interesting than the research choices in Xenonauts 1.
Regional Infrastructure & Population: Under this strategic design, the X1 system of building bases in various regions doesn't really fit in any more. However, I'd like to preserve an element of base-building that exists beyond the abstract main Xenonaut base; I think we can do that by adding infrastructure to each defensive perimeter.
These ideas haven't been tested so they remain just ideas right now, but we'd like to have buildings in each perimeter that they player can build and buy. A lab provides a fixed amount of science, but buying a lab behind the final defensive line would be much more expensive than buying one behind the third line. If you can hold it long enough, the cheaper lab would be a much better investment. But doing so might force you into proliferating tech earlier than you might have wanted to, etc.
Similarly, things like the intelligence level (how many days you can see into the future on the Timeline) could be tied to buildings constructed in each perimeter. That gives the player choices about how much they want to invest in defending a specific defensive line.
The other mechanic I'd like to implement in some form is an evacuation mechanic for the local civilian population in each perimeter. A certain number of turns would be required to evacuate the civilian population, but launching an evacuation too early would prematurely abandon all the local infrastructure and deprive yourself of resources you would otherwise receive. However, allowing civilians to be overrun and harvested by the aliens is also bad news for humanity, as it gives the aliens major bonuses. Maybe this could be made more interesting if there's a random element to how smoothly the evacuation goes; so in some situations players may find themselves needing to hold out longer than they originally expected.
Overall:
That's not a full explanation of everything in the strategy layer, but hopefully it explains the basic principles that we are working towards. I've been working hard on a design that puts the actions of the Xenonauts in a wider strategic perspective and I think the "defensive perimeter" system and the proliferation mechanics mean that the player will have to think about more than just their own soldiers.
Playtesting suggests that the basic strategic mechanics are good fun, and they should also take Xenonauts 2 in a rather different direction to that of the other X-Com successors that have been and gone. X1 always had the trappings of a somewhat realistic military wargame, but the mechanics never really matched up ... hopefully this time around we'll be able to deliver on it.
This is all I'll be revealing about Xenonauts 2 for now, but I just wanted to thank everyone for their patience and assure everyone that things are coming along nicely at this end. It may be disappointing for some that we're not announcing quite as quickly as we initially suggested we would, but hopefully this post gives you some insight as to why that is (and reveals just enough to keep you interested!)
