Fun quick gunplay. The maps seem very similar to each other and the game seems very one dimensional. I think that's the point. It is a simple game where you fight and upgrade till you become over powered. I have only played for 2 hours, but I just find myself frustratingly running around trying to find boxes and portals. It has not been very fun. I will probably give it another go a couple times, but I dont think I will change my mind on this one.
