[Update]: The Gears of War flavored XCOM game, Gears Tactics, has now landed onto PC and Xbox One - just in case you're looking for a little bit more turn-based action!
Instead of a full-blown XCOM experience, the newly released XCOM: Chimera Squad is more of an action-orientated spin-off. The missions are shorter and have much simpler objectives, the combat is more frequent and hectic due to the breaching mechanic, while the pre-made characters offer a bit more personality and unique combat options when compared to the usual XCOM grunts.
If you're wondering just what all of this might look like in gameplay terms, you can get a pretty good impression through two of the recent trailers. The first one sets up the various characters and the overall storyline, while the second one is all about the actual battles. Have a gander:
While not exactly long or even close to replayable as XCOM 2, XCOM: Chimera Squad does have one massive advantage working in its favor - its price tag. Until May 1st you can grab it for a mere €10 as a sort of early adopter bonus, with the price going back up to €20 afterwards. So if you're even remotely curious about turn-based strategy games, for €10 I think XCOM: Chimera Squad is a pretty good introduction.
You can learn more about XCOM: Chimera Squad, as well as potentially grab yourself a copy, over at Steam. Have fun!
