Last updated: March 2026
DEFRAG offers 6 distinct game modes for every playstyle: Free-for-All (classic solo deathmatch), Team Deathmatch (coordinated team combat), Gun Game (progress through all 6 weapons per kill), Domination (capture and hold strategic control points), Capture the Flag (steal the enemy flag, score limit of 3), and Search & Destroy (round-based bomb mode with no respawns). Select your mode from the lobby and join matchmaking or browse 4 official server lobbies.
Master all 6 weapons, each with unique fire rates, damage profiles, and optimal engagement ranges: Rifle (versatile all-rounder), SMG (high fire rate for close quarters), Shotgun (devastating at point blank), Pistol (reliable sidearm), Sniper (long-range precision with scope via right-click), and Knife (silent melee with instant kill from behind). Switch weapons with number keys 1-6.
Earn XP from every match to progress through 20 ranks from Recruit to Commander, each unlocking new profile badges. Compete on the global ELO leaderboard where wins against higher-rated opponents earn more points. Unlock killstreaks like UAV for enemy position reveals. Customize your look with cosmetic bundles from the in-game shop.
