Knockback Wins Fights, Not Just Damage
Gun Mayhem takes platform fighting and swaps out traditional health bars for pure knockback, echoing the Super Smash Bros. formula but built entirely around guns. Every shot pushes your target back a little, and enough cumulative knockback sends them flying clean off the platform's edge for a full knockout — meaning a weak pistol landing repeated hits near an edge can be just as lethal as a powerful rocket launcher landing one clean shot. Perk boxes scattered across the stage grant temporary boosts, and switching weapons mid-air while juggling your own momentum lets skilled players chain together combos that push enemies toward the edge faster than they can recover. You can even use your own weapon's recoil deliberately, firing downward to boost yourself back onto the stage after a risky jump, or firing at an airborne opponent to redirect their trajectory straight toward the void. Custom loadout options let you build toward weird, personal playstyles once you've got the fundamentals down, and despite the surface-level chaos, real skill consistently separates good players from button-mashers.
Controls: Move, Jump, Shoot, Manage Recoil
Use the arrow keys or WASD to move and jump between platforms, and aim with the mouse or a secondary key set depending on the control scheme loaded, firing to both damage and knock back opponents. Switching weapons mid-air is a core skill, since different guns serve different purposes — some knock straight back for edge-guarding, others knock upward for aerial combos.
- Track cumulative knockback on both yourself and opponents rather than treating every hit as equally dangerous.
- Use your own weapon's recoil deliberately to recover position after a risky jump toward the edge.
- Grab perk boxes proactively, since a temporary boost at the right moment can swing an entire exchange.
- Switch weapons based on the situation — edge-guarding calls for different guns than aerial combos do.
- Stay near the stage's center when possible, since edge positions are inherently riskier under sustained fire.
