Gun Mayhem 2
Two players, one keyboard, knock them off the map.
About Gun Mayhem 2
Gun Mayhem 2: More Mayhem is a 2012 arena shooter by Kevin Gu. Stick figures with guns face off on a few floating platforms, and the goal is not to wear down your opponent's health but to knock them off the map. Every shot pushes the target backwards, so the closer they are to the edge, the more dangerous each hit becomes. Each player has a limited number of lives; lose them all and you are out.
There is a large arsenal to unlock – pistols, shotguns, machine guns, sniper rifles and stranger things – plus grenades and mines, perks that change how you play, and a wardrobe of hats and colours. You can fight through single-player missions, take on computer bots, or play against a friend on the same keyboard.
How to play Gun Mayhem 2
- Move and jump with the movement keys, double-jump to recover when you are knocked away.
- Shoot to push opponents towards the edge; throw grenades for big knockback.
- Pick up weapon drops during the round.
Click inside the game first. The exact keys for each player are shown in the game's own controls screen.
The two-player classic
Few Flash games are as good with two people side by side. For more stick figure action, see the stick figures & action box, or the two-player throwing duel Fleabag vs. Mutt.
Stuck? Hints, gentlest first
Hint 1 – knockback is everything
You do not win by damage but by pushing opponents off the stage. Weapons with strong knockback are worth more than fast ones.
Hint 2 – stay central
Fight from the middle of the map. Near the edges, a single shot can send you flying off.
Hint 3 – use the drops
Weapon crates and power-ups fall during the match. Grab them when it is safe – a better gun often turns the round.
Gun Mayhem 2: More Mayhem by Kevin Gu came out in 2012 and became the game two friends played on one laptop. Its quick rounds, silly hats and arsenal of weapons made it a lunchtime classic for years.
