If you played and enjoyed the original Xenonauts, you may be interested to know that the Kickstarter for the sequel Xenonauts-2 has now gone live: https://www.kickstarter.com/projects/69341191/xenonauts-2-strategic-planetary-defence-simulator/
Full details of the new game are available on the Kickstarter page, along with a free alpha demo of a tactical combat mission - we've still got plenty of work left to do, but hopefully you can see the improvement!
Xenonauts-2 is not a chronological sequel to Xenonauts, but rather an updated portrayal of similar events. We've moved to a much more modern engine (Unity) and improved the quality of the visuals, and we're making all sorts of changes to the design to fix some of the gameplay issues that meant not everyone enjoyed Xenonauts as much as they could have!
We're expecting Xenonauts-2 to move into closed beta in about three months, followed by a general Early Access release on Steam / GOG before the end of the year.
The more money we can raise on Kickstarter and in Early Access, the longer we'll be able to spend adding new content to the game and fixing the bugs / balance issues / usability issues reported by the community. If you enjoyed Xenonauts, we'd appreciate your support in making a sequel that builds on those foundations!
