Greetings and apologies for the slight lateness of this update - the team wanted to finish a few things before putting it up.
Public Builds
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.
Armour Up
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.
Air Supremacy
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.
Morale Boost
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!
Odds and Ends
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.
Many thanks for reading and for staying up-to-date with our work - as ever please do join us on Discord, the forums or the Steam community if you have any questions.
