What Is Gun Mayhem 2?
Gun Mayhem 2 is a free, browser-based platformer shooter developed by Kevin Gu, and the direct sequel to the original Gun Mayhem. The core idea carries over from the first game: instead of a health bar, you win by knocking opponents off the edge of the platform entirely – shoot them hard enough or catch them with an explosion at the right moment, and they go flying off into the void, costing them a life. Whoever’s still standing after everyone else runs out of lives wins the round.
What makes Gun Mayhem 2 a genuine step up from the original is the sheer amount of content packed in: a 16-mission campaign, seven custom game modes you can mix and match, a full challenge mode for practicing specific weapons, character customization, and selectable perks that change how you play. It supports up to four players on a single keyboard, making it one of the better couch multiplayer browser games out there.
How to Play Gun Mayhem 2
- Pick your mode. Jump into the Campaign for structured missions, set up a Custom Game with your own rules, or head into Challenge Mode to sharpen your aim with a specific weapon.
- Move and jump around the platform. Staying mobile is essential – standing still near the edge is the fastest way to get knocked off.
- Grab weapons and power-ups from crates. Crates drop into the arena throughout a match, giving you access to better guns, explosives, and other tools.
- Shoot to push, not just to score. Every hit applies knockback. Chain shots together, especially near the edge of the platform, to send an opponent flying off entirely.
- Use bombs and secondary weapons wisely. Explosives can hit multiple opponents at once or catch someone off guard who’s trying to recover from a knockback.
- Watch your own position near the edges. Since falling off costs you a life just as much as it costs your opponents, don’t get greedy chasing a kill right at the platform’s border.
- Outlast everyone else. Once opponents run out of lives, they’re out – the last player or team standing wins.
Controls
| Action | Player 1 | Player 2 | Player 3 | Player 4 |
|---|---|---|---|---|
| Move | Arrow Keys | WASD | Numpad 7 / 8 / 9 | Numpad 1 / 2 / 3 |
| Shoot | Z | T | Numpad * | Numpad 0 |
| Bomb / Secondary Weapon | X | Y | Numpad – | Numpad . |
All of these controls can be remapped from the in-game Controls & Settings menu if you want a different layout – useful if you’re setting up a 3 or 4-player match and need to adjust who uses which keys. On mobile and tablets, on-screen touch controls handle movement and shooting for single-player modes.
Game Modes
Campaign
A 16-mission single-player campaign that gradually escalates in difficulty, including boss fights and unique themed challenges like “Invisible Man” and “Dynamite Only” mission variants. Only the first two missions – Tutorial and Easy AI – are unlocked at the start, with the rest opening up as you progress.
Custom Game
Set up your own match using seven different sub-modes:
- Last Man Standing – Free-for-all. Everyone fights until only one player is left.
- Last Team Standing – The same idea as Last Man Standing, but played in teams alongside friends.
- Survival – Fight off increasingly powerful robot enemies with only five lives to work with.
- 1 Hit 1 Kill – Everyone’s armed with the De-materializer, a weapon that eliminates an opponent in a single hit.
- Gun Game – Progress through a set sequence of weapons as you rack up eliminations.
- Gun Game Reversed – The same idea as Gun Game, but you start with the most powerful weapon and work down to weaker ones.
- Jetpacks – Everyone gets a jetpack to fly around the arena – just keep an eye on your fuel.
Challenge Mode
Seven focused training scenarios that test your accuracy with one specific weapon at a time, without any crates or power-ups to rely on: Handgun Training, SMG Training, Shotgun Training, Assault Rifle Training, Sniper Training, Dynamite Toss, and Crate Collection. Clear targets as fast as possible to earn a star rating for your performance.
Perks and Customization
Before heading into battle, you can customize your character’s look – color, facial hair, and outfit – to stand out from the crowd. You can also select a perk that gives you an edge in battle; the triple jump perk in particular is a strong pick, giving you extra aerial mobility to dodge incoming fire and reposition near dangerous edges.
Tips and Tricks
- Stay away from platform edges unless you’re finishing a kill. Edges are where knockback actually matters – lingering near one without a good reason just puts you at risk instead of your opponent.
- Learn the triple jump perk early. The extra air mobility it provides makes it much easier to recover from knockback and avoid getting cornered near an edge.
- Prioritize crates in the middle of a match, not at the very start. Rushing for the first crate that spawns often exposes you to opponents who are already in position – let the fight develop a little first.
- Save bombs for crowded moments. Since explosives can hit multiple opponents, they’re most valuable in Last Man Standing or Survival modes when several players or enemies are grouped together.
- Practice in Challenge Mode before Campaign. Since Challenge Mode strips away crates and power-ups, it’s a focused way to build raw aim with a specific weapon before relying on it in a real match.
- Coordinate with teammates in Last Team Standing. Since knockback stacks the closer an opponent is to the edge, teaming up shots on a single target near the border is far more effective than everyone attacking separate opponents.
- Remap controls before a 3 or 4-player match. The default numpad-based controls for Players 3 and 4 can be awkward on some keyboards – check the Controls & Settings menu ahead of time so nobody’s fumbling for keys mid-match.
