Xenonauts 2 - October Development Update

Couchpotato spotted the October update for Xenonauts 2:

Xenonauts 2 October Development Update!

It's time for our regular Xenonauts 2 development update. Here's what the development team has been busy with this month!

Milestone 2
Our main focus this month has been Milestone 2, which is undergoing testing on the Experimental branches. This is now feature complete - we're concentrating on bugfixes and balance changes while we wait for a few more maps / art assets / research texts to be completed. We're expecting to be able to release it onto the default Steam branch a couple of weeks from now, about halfway through November.

Milestone 2 contains a lot of updates, including several new types of tactical mission, a new UFO type, and some significant changes to the early part of the campaign to expand the role of the Cleaners (there's more details about this in our previous development update).

Air Combat Rebalance
One thing worth mentioning in more detail is our rework of the air combat. We've implemented a more freeform equipment system for Xenonaut aircraft and then rebalanced the air combat itself so it rewards skillfully maneuvering your aircraft in a similar way to the original Xenonauts, while also trying to remove a few of the more abusable tactics (e.g. it's no longer possible to continually use evasive roll to circle-strafe around an enemy).

This means the overall balancing pass has touched almost every part of air combat. We've tried to create distinct identities for all the different types of weapons you can fit on your interceptors, make the different UFOs pose different challenges to the player, and added some new UFO weapons and aircraft equipment to increase variety.

Of course, many people prefer to simply autoresolve the air combat - and this is one of the ongoing balance issues we're aware of in Milestone 2. Making the game playable for people who only use autoresolve has led to the air combat being a little too easy for people who use only manual autoresolve, so we're going to be working to fix that over the next week or two.

AI Improvements
We've also started upgrading the AI this month. We begun by focusing on the civilian AI, as they currently don't behave in a very realistic way - as MANY players have noticed! I'm not sure if we'll have a patch ready for Milestone 2, but if not then we should have noticeable improvements in place for Milestone 3.

Additionally, many of the issues we've found with the civilian AI were caused by problems with the general AI model - which means fixing them will make the aliens a bit smarter too!

Loading Times & Unity Upgrade
Another thing we've been actively working on is improving loading times, with the eventual goal of reducing load times by roughly 50%. The good news is that we're making steady progress here, but the bad news is that players are unlikely to see any improvements until Milestone 3.

This month we experimented with stripping some further data out of our saved game format and found this sped up loading times by 25%-30% on our current (very outdated) version of Unity. However, when we tested this change in a more modern version of Unity, we found something interesting: load times were sped up by 25%-30% even if we disabled our change. It turns out recent versions of Unity have optimised that part of their loading process already.

As upgrading Unity will also bring a lot of other improvements to the game (e.g. better performance, proper support for borderless window mode, etc), we're planning to do that as part of our plans for Milestone 3. In the meantime, we're working on multithreading as a way to deliver the remaining ~25% loading time reduction.

Conclusion
Although there's plenty of smaller things I could talk about, I'll end things here. I think we've had a productive month overall, and personally I've particularly enjoyed seeing progress towards fixing some of the largest remaining problems raised by players at launch (slow loading times, bad civilian AI, the air combat needing more work).

As always, thanks for reading - I'll write another post next month!
