This game contains sustained depictions of death and injury to human-like characters. The player stands in a stationary position and must defend themselves against hordes of enemies. These enemies range from dinosaurs, to zombies, to robots and all feature different reactions to the violence. Whilst the majority of the violence in the game is non-realistic in nature with characters quickly dissolving after being defeated, some of the more human enemies have realistic looking reactions to the violence. The most pertinent example of this is the zombie enemies. When they are shot blood appears on impact and their bodies fall limply to the floor. If you perform a headshot the characters head will blow up and a small amount of blood will come from the wound before they quickly fall to the floor and disappear.
