As a cybernetically enhanced elite Unit 13 soldier, you are suddenly woken up during a zombie virus outbreak on the ESS Meridian starship. You find out the ship is headed straight to Earth with the virus aboard - in effect a lethal biological weapon. You must stop this threat, no matter what.
Dead Effect is a first-person shooter with a 'bullet time' feature, where you can slow down time briefly. Your first weapon is a stun gun that has infinite uses, but needs time to recharge between shots. You can also carry one one-handed and one two-handed weapon as well as one type of explosives.
