Deadshift is a driving game where the obstacles are the point. Twenty missions in a quarantined arena ask you to smash a path through the horde, collect supplies, pick up survivors and reach the extraction ring before the clock runs out. Collisions throw zombies into ragdolls with enough enthusiasm that the game is really about choosing which crowd to drive into. Vehicles can be painted and upgraded for engine, armor and nitro, and armor is the upgrade that actually changes how the missions play.
