A top-down survival shooter where aiming is automatic and positioning is everything. Waves arrive without pause, the crowd grows, and the only real decision is which direction to retreat in before you are surrounded. Between rounds you craft weapons, upgrade the character and take perks, which is where the run is actually won or lost. Solo it is a test of patience; played in co-op it becomes a conversation about who is drawing the swarm and who is supposed to be clearing it.
