Dirty Bomb casts its team-based shooter in a London battered by a series of radiological attacks. The Central Disaster Authority is trying to restore the city, while the criminal syndicate Jackal interferes with and steals its technology. Mercenaries are hired by both sides, placing players amid a conflict shaped by competing interests and a bleak, mercenary-minded tone.
Combat is built around fast, demanding team play rather than aim assistance or controller support: the store description emphasizes player skill and reaction, and warns that the game offers little hand-holding. Its roster features more than twenty distinct Mercenaries, each with individual abilities and attributes. Choosing a character is therefore part of the game’s tactical identity, while cooperation is central to surviving its challenging PvP matches.
Dirty Bomb offers two modes with different match structures. In Objective, teams fight through sections of the city, completing tasks and trying to reach the finale before time expires. Stopwatch adapts that objective format for competition, having teams switch sides mid-match to compare how quickly each can finish.
