Haven't had this much fun on a co-op shooter in ages. It's visceral, pretty, fun, and funny. As has been said many times before, this is the best Starship Troopers game out there at the moment. It's so damn satisfying watching a horde of bugs get slowly minced to pieces by the heavy machinegun fire of your squad, and blowing the remnants sky-high with an orbital strike.
Yes, the matchmaking is not ideal at the moment, but it's actively being worked on by the devs. It works fine when playing with friends, but if you're joining randoms it'll take quite a few tries before you connect. but that's about the worst part that I've experienced.
