He all, apparently Kill Team came out (thought it wasn't out until the end of the month), so of course I downloaded it. It's a fairly solid little two-stick shooter, not the best but I don't feel like I was just scammed out of 10 bucks. I've played two levels so far tonight, one as the Librarian and one as the Sternguard Vet (which is apparently THQ-speak for Devestator), and enjoyed them both. Felt like the Librarian was better off for solo play since he's more melee-centric and his special power is much more of a crowd-clearer. The Sternguard's special is to just shoot his weapon really, really, really fast for a few seconds.
TL;DR - Buy the game if you like it when the Emperor's Angels cleanse a small part of the galaxy with lots and lots of bullets and sword-related tomfoolery
