The guide

Overview

Play the original Gun Mayhem game where the goal is to stay on the island without getting knocked off. Choose your weapon wisely so that you can knock your opponents off. Grab creates to to get firearm upgrades.

What it's like to play

Shooting games are about aim and timing, and not much else gets in the way. Targets appear, you point and fire, they disappear or they shoot back. Ammo matters. Position matters. Some games are side-on with waves of enemies, others put the crosshair in the middle of the screen. Either way, a session is a steady escalation until your reflexes run out.

How to play

1Find the fire and aim controls on the start screen; usually the mouse aims and clicks fire on desktop, and tapping the target fires on phones.
2Shoot the nearest or fastest threat first, not the biggest. Big targets usually take several hits anyway.
3Reload or switch weapons during quiet moments rather than in the middle of a wave.
4Keep moving if the game allows it. A stationary player is the easiest target in any shooter.
