Madness Online is a 2D multiplayer survival shooter developed by Madguy777, released in March 2026. Inspired by the iconic Madness Combat series, the game drops players into an infinite procedurally generated world filled with zombie hordes and hostile human opponents.

The core loop revolves around scavenging resources, crafting weapons and gear, and building fortified bases — all while fending off relentless enemy waves that grow more dangerous over time. What keeps sessions unpredictable is the combination of PvP and PvE pressure.

You're never just fighting zombies — other players can be allies or threats. Co-op teams can split roles between scavengers, builders, and defenders, which adds a tactical layer uncommon in browser-based shooting games.

As an HTML5 game, Madness Online runs directly in your browser without installation, making it one of the more accessible survival shooters available right now. Movement uses WASD, while the mouse handles aiming and shooting (left click to fire).

Press Space to dodge — a critical defensive move that grants temporary invincibility frames during enemy rushes. Reload with R before your magazine empties, and switch between carried weapons using Q. Press E to interact with objects like loot drops, crafting stations, or doors.

Open your inventory with B to manage resources, craft equipment, and organize your loadout. Use Enter to chat with other players, and M to pause. Survival is the only metric that matters.

Each session begins in a procedurally generated world where you spawn with minimal equipment. Your immediate goals are to scavenge materials, find or craft a weapon, and establish a defensible position.

Zombie waves escalate over time, and hostile players add a second layer of danger. There is no fixed endpoint — you survive as long as your resources, reflexes, and base hold out. Materials are scattered across the map and can be collected by pressing E near them.

Your inventory (B) has limited space, so choosing what to carry is a constant decision. Gathered resources feed into the crafting system, allowing you to build weapons, ammunition, and defensive structures.

Prioritize crafting essentials early — running out of ammo deep in hostile territory with a full backpack of raw materials is a common way new players die. Once you've accumulated enough resources, you can construct a base to serve as a safe zone and respawn anchor.
