Is there a plot?
The world is held ransom by an evil organisation with a secret weapon: waves and waves of expendable men. You are an operative in an elite task force with the critical mission of saving the world, armed only with a hammer, a handful of guns and a million billion bullets.You will need to memorise the intricate patterns of the bullet-spewing giga-bosses, time your hammer swings against charging berzerkers and practise your circle-strafing against armies of mechs.
Jump, shoot, dodge, explode, hammer, shoot, explode, crush and explode your way across teeming jungles, devastated cityscapes, evil labs, stinking sewers, rickety elevators and silent train yards against hundreds of enemies per level.
