Winning a round in Gun Mayhem requires more than just depleting an opponent’s health; you must physically knock them off tiny floating platforms. Supporting 1 to 4 players on a single keyboard, this cartoony 2D platform arena shooter relies on bullet recoil and explosive force to push rivals over stage edges. Falling off the island map costs the round, making stage positioning and knockback potential far more critical than pure firearm damage.

Floating Arenas and Firearm Customization

Fights unfold across 12 floating island maps, where narrow footing makes every step hazardous. Gun Mayhem features an arsenal of over 60 firearms, which players can test fire directly inside the dedicated Gun Library mode.

Players can progress through a cooperative or solo Campaign mode, completing escalating chapter objectives against computer bots to unlock firearm upgrades. For custom matches, players can configure outfits, adjust player counts, and select specific game modes

• Last Man Standing: Traditional elimination matches where staying on stage secures victory
• One Shot One Kill: High-stakes firefights where every shot carries maximum lethal threat
• Gun Game: Dynamic weapon cycling that changes your gun upon scoring eliminations
• Duck Defense: Specialized objective mode challenging players to protect targets under heavy fire
