The demo for “Persistence” contains depictions of realistic looking violence towards human-like characters. The player fights against various zombie-like characters. The primary weapon used acts much like a taser does by electrocuting and incapacitating the enemy. The enemies shout and shake in pain whilst being electrocuted. If you attack them numerous times it kills them and their bodies fall to the floor. The bodies then remain on the floor for the rest of the level.
