Gun Mayhem 2: the shooter where the bullets push and the floor is the enemy
Gun Mayhem 2: More Mayhem is the 2012 sequel to Kevin Gu's Flash brawler, and it keeps the one idea that made the first game work: there is no health bar. A pistol round nudges the fighter it hits, a shotgun blast throws them, and the more punishment they have soaked up the further each hit sends them, until one shove too many carries them past the edge of a floating platform and off the bottom of the screen. That costs a life, they drop back in from above, and the scramble starts again. Ten lives each in a default custom match, five in Survival, and whoever still has one at the end wins. The sequel stacks more on top of that: nine new maps next to the twelve classic ones, a weapon library sorted into SMGs, snipers, shotguns, assault rifles and oddities, a campaign of sixteen missions and a set of timed weapon challenges with star ratings.
What makes it a party game rather than a solo shooter is the keyboard. Four fighters can share one keyboard at once: arrow keys and Z/X for the first, WASD and T/Y for the second, and two numpad clusters for the third and fourth, all rebindable under Options. The custom game screen lets you fill any of the four slots with a person or an AI player and pick from seven modes, from plain Last Man Standing to Gun Game, where every kill hands you the next weapon on the list, and Jetpacks, which gives everyone a slowly recharging burst of flight. The copy on gunmayhem2.org is the original SWF running through Ruffle, so nothing installs, it works on a Chromebook, and the shove physics are the ones the game shipped with.
Controls & mechanics
| Action | Control | Purpose |
|---|---|---|
| Move and jump (P1) | Left / Right, Up to jump, Up again in the air | The double jump is how you get back to the stage after a hit; Down drops through a thin platform |
| Shoot (P1) | Z (hold for automatic weapons) | Knocks the target away from you; the crate gun you are holding decides the push and the ammo |
| Dynamite (P1) | X | Lobs a stick with a short fuse; the blast throws anyone near it, including you |
| Player 2 | W A S D, T to shoot, Y for dynamite | Same rules as player 1 on the left side of the keyboard |
| Players 3 and 4 | Numpad / 7 8 9 with * and −; numpad 5 1 2 3 with 0 and . | Both clusters fit a full-size keyboard; rebind them under Options on a laptop |
| Menus | Mouse | Mode, map, lives, crates and pickups are all set by clicking before a match |
How to stop falling off in Gun Mayhem 2
- Fight from the middle, not the edge: Every hit pushes you further than the last, so a fighter standing at the lip of a platform needs only one shotgun blast to go over. Take the centre platform and let the bots come to you; a hit that lands while you have floor behind you costs nothing.
- Save the double jump for the recovery: When a shot knocks you off the stage you are not dead until you fall past the bottom. Wait until you are level with the nearest platform, then jump twice toward it. Spending both jumps early, while you are still rising from the hit, is the most common way to lose a life.
- Match the gun to the mode: Snipers and revolvers hit hardest per shot and are the pick for Last Man Standing, where one big push ends a life. In Gun Game the weapon changes every kill, so learn the fast SMGs too: they push less but keep the target airborne and away from the platform.
- Throw dynamite at the platform, not the fighter: The fuse is long enough that a moving target walks away from a direct throw. Land the stick where the bot will be when it detonates, usually the platform it is jumping to, and stand clear yourself: the blast is symmetrical and will happily launch the thrower.
Key features
- Four on one keyboard: Up to four human players at once, each with their own key cluster, and AI players to fill the empty slots.

- Seven custom modes: Last Man Standing, Last Team Standing, Survival, 1 Hit 1 Kill, Gun Game, Gun Game Reversed and Jetpacks, with crates, pickups and the life count as toggles.
- Twenty-one maps: Nine new stages (Jungle, Ski Lift, Space Station, Avalon, Venice, Alien Planet, Sub Base, Highway, Castle) beside the twelve from the first game.
Game info
- Title: Gun Mayhem 2
- Developer: Kevin Gu
- Category: Platform Shooters
- Platform: Web browser (HTML5)
- Players: 1–4 on one keyboard, bots fill the rest
Pro tip: The campaign's difficulty is in the modifiers, not the bots. Triple Jump gives everyone a third jump, so a knockback that would normally be fatal is not, and you have to push harder; Dynamite Only takes the guns away entirely; Too Fast doubles the pace; De-materializer hands every fighter a gun that kills on the first touch. Read the mission name before you pick a starting weapon, because the loadout that clears Easy AI is wrong for most of them.
Frequently asked questions
What is Gun Mayhem 2: More Mayhem?
A cartoon 2D platform shooter by Kevin Gu, released in 2012 as the sequel to Gun Mayhem. Fighters have lives instead of health: bullets and dynamite push, and a fighter who is pushed off the stage loses a life. It has a sixteen-mission campaign, timed challenges and custom matches for up to four players.
What are the controls?
Player 1: arrow keys to move, Up to jump and double jump, Down to drop through platforms, Z to shoot, X for dynamite. Player 2: WASD, T and Y. Players 3 and 4 use the numpad. Every key can be changed under Options on the title screen.
Can I play it with friends?
Yes, on one keyboard. Custom Game lets you set any of the four slots to a human or an AI player, pick a mode and a map, and set the number of lives. There is no online multiplayer; the game predates it.
Is this the Flash version?
Yes. It is the original Gun Mayhem 2 SWF (version 1.1) served from this site and run by Ruffle, an open-source Flash Player emulator, inside your browser. No plugin or download is needed.
Does it work on a phone?
It loads, and touch buttons are overlaid for player 1 (a d-pad, fire and dynamite), but it is a keyboard game at heart. A laptop, desktop or Chromebook with a keyboard is the way to play it, and a full-size keyboard with a numpad is needed for players 3 and 4.
