The forces of hell are here!
Why? Dunno.
How? I don't think it matters.
All that matters is that you gotta fight them, right now!
In this game, you play as one of 3 agents fighting off increasingly large hordes of enemies! Every agent has weapons and abilities unique to them, and you have to use them to them to their fullest abilities to get as high of a score as possible! The faster you kill enemies, the higher your score multiplier gets! But don't let off the pressure, because if you do, you'll get swarmed and overwhelmed by the forces of hell!
