Godawful.
Not only is there nothing new added from the previous versions, it has degenerated.
Gameplay is tedious (kill X enemies -which spawn from a single point- to open door), levels are mostly simple corridors, weapon management is horrible (worsened by the fact that you run out of ammo constantly), and the lack of a health bar adds to the unneccessary frustration.
Only got a card & badges because of the other games in the series. Next time play the game before assigning it achievements.
Kongregate has jumped the shark.
