The "Grunts" are a motley collection of people participating in the games. While some of the contestants are people greedily and selfishly seeking glory or riches, many of the enemies were former citizens of Varrigan City unwillingly forced to participate in Deathwatch. The majority of the contestants use any available weapon on hand, with weapons such as lead pipes and baseball bats with spikes driven through them. However, in some areas, the crudely armed thugs yield to various unique enemies. These enemies are set up in accordance with the theme of the stage, with ninjas featuring in the Asia Town region, zombies predominating in the Mad Castle area, and armored security guards armed with stun batons and tower shields appearing in the "alien research" area.
