When it comes to turn-based tactics, there's still one undisputed king of the genre: XCOM. If you've never experienced its brand of tense, alien-killing strategy before—or if there's a game or two in the series you skipped—then the good news is that today is a very cheap day to catch up.
Humble Bundle's new XCOM Complete offer is appropriately named—it really does include every XCOM game for just $10/£7.51. Well, technically excluding the mobile game. And that one Hasbro made where you played by email or something. But all the real ones!
