Characters are equipped with a signature weapon such as large calibre automatic weapons, large hammer or a spiked flaming medieval mace. The violence, whether caused by a weapon or hand to hand combat is identical, there are lots of blood splashes and a character falls to the ground. There is no visible injuries and once killed a character disappears. Although characters do not react realistically to the violence, there are sustained depictions of death and injury.
