If you're a fan of the 4-man horde shooter "L4D2" formula, you'll have a blast. The levels and atmosphere are gorgeous, and the 4 classes are all distinct yet equally useful and fun to play. However, I can't rate this any higher than ★★★★ because of the late game's PUNISHING craft system that relies heavily on RNG with few options against it. Play the game through to level 30, but just don't try min-maxing or you'll waste tens of hours that aren't worth it.
