Madness Online

Mission briefing

Madness Online is a brutal 2D top-down multiplayer survival shooter set in a procedurally generated infinite world. Players must navigate a hostile, apocalyptic environment by fighting off relentless waves of zombies and enemy entities. The game blends intense, fast-paced gunplay with deep survival mechanics, allowing players to gather resources, craft essential gear, and construct fortified bases. Featuring dynamic combat with dodge mechanics and an expansive inventory system, players can team up with friends to build and survive together, or face the unforgiving world solo.

Launch orders: press Launch mission above and the game loads on this page itself — nothing downloads and no form stands between you and the first move. It is designed for a flexible screen and takes its orders from mouse, keyboard or touch, depending on the mission. It adapts to both upright and wide screens, so phones, tablets and desktops all frame it sensibly. If it offers a fullscreen control, use it — a fight this size deserves the whole screen.

Field notes for zombie operations

• The horde is a resource problem wearing a horror costume. Every bullet spent on one zombie is one not spent on the five behind it — line them up, funnel them, make each shot plural.
• Barricades buy seconds, not safety. Spend those seconds on the next line of defense or the exit, never on admiring the first one.
• Noise is a beacon. Loud weapons solve the zombie in front of you and summon the street behind you; the quiet option is often the shot you do not take.
