So since quite a number of people (including myself) are pissed off with 2K's upcoming 1st person rendition of X-COM, we will have to look into other alternatives to satisfy our want for turn-based tactical combat. So, recently I found out that there is an independent group of developers in the UK making their own spiritual successor to X-COM. It is called Xenonauts.
It is supposed to keep the same basic elements that made up the gameplay of the X-COM series. It will also sill keep the basic story-line that you control a multi-national force on Earth set-up to repel an invading alien incursion. In Xenonauts, however, the story is set during the Cold War and displays an alternate history where Russia and the US are forced to cooperate with this new threat.
You can read the whole story at their website:
Unfortunately the game is still early in development so there aren't many pics that I have seen. They said they announced the game early when they heard that people were annoyed with 2K's version of X-COM. In any case, let's hope for the best for this upcoming game.
