Dirty Bomb is a free-to-play multiplayer first-person shooter that emphasizes raw skill and teamwork in a chaotic post-disaster London setting. Released initially in 2015, this PC title pits mercenaries against each other in objective-driven matches, where quick reactions and strategic coordination determine victory. Without aim assist or controller support, it demands precision from players, making it a standout choice for those seeking a pure FPS experience.
Gameplay
In Dirty Bomb, matches unfold on maps inspired by a ravaged London, with teams divided into attackers and defenders. Attackers focus on tasks like repairing and escorting an Extraction Vehicle (EV), planting C4 charges to destroy targets, or stealing data cores. Defenders work to prevent these actions, often by holding positions or disrupting progress. Players choose up to three mercenaries before a match, each with unique abilities, attributes, and loadouts, such as deploying ammo packs, healing stations, or sentry guns. Switching between selected mercs happens between respawns, encouraging adaptable strategies. Reviving downed teammates adds a layer of teamwork, while side objectives provide bonuses like faster EV repairs. The absence of aim assist heightens the skill ceiling, rewarding accurate shooting and fast decision-making in fast-paced encounters.
Mechanics draw from class-based shooters, with over 20 mercenaries offering varied roles, from assault types with high firepower to support classes that bolster allies. Factions include the Central Disaster Authority (CDA), government-backed defenders maintaining order, and the Jackal syndicate, criminal attackers seeking to exploit technology amid the chaos of dirty bomb attacks.
Game Modes
Dirty Bomb features two primary game modes that highlight its competitive team-based structure. Objective mode tasks attackers with completing a series of map-specific goals before the timer expires, while defenders aim to stall them. Success depends on coordinated pushes and defenses across multi-stage maps like Chapel or Terminal.
Stopwatch mode adds a layer of rivalry by having teams alternate between attacking and defending in rounds. The team that completes objectives faster wins, with potential for draws or overtime if times match closely. This mode suits competitive play, as it measures efficiency and adaptability. A former mode called Execution, which involved no-respawn rounds focused on eliminating the enemy or handling pylons and C4, was removed in updates.
Mercenaries and Abilities
The roster of over 20 mercenaries forms the backbone of Dirty Bomb's customization. Each merc brings distinct abilities, such as airstrikes, molotov cocktails, or deployable turrets, tied to their class. Players earn credits through matches to unlock loadouts and items, with recent updates enabling Steam Trading for cosmetics and increasing credit earn rates to around 70 per minute based on performance. This system allows for personalized playstyles, whether favoring aggressive rushes or defensive setups.
Is It Worth Playing?
Dirty Bomb remains active in 2026, with servers online and recent updates like the removal of RADs currency, converted to credits, and the reintroduction of items such as Obsidian Operatives and event cases. Player reception on Steam is Very Positive, with 81% positive reviews from over 34,000 English-language entries, and recent reviews at 95% positive from a smaller sample in the last 30 days. If you enjoy skill-focused multiplayer FPS games with objective-based teamwork and no hand-holding, it's worth trying, especially since it's free. However, the player base is smaller now, which might lead to longer queue times, but the core action holds up for dedicated fans of intense, uncooperative shooters.
