Story:

Crazy monsters lurk in the dark of night, trapped behind the rusty iron graveyard gates. As the Gate Keeper, you must keep the monsters behind bars and stop them from escaping by any means necessary.  This is classic castle defense with a twist: no gun turrets, blocks or speed reduction - just all out ATTACK with explosive weapons and action-packed combat!
