Survivor.io

Downtown is overrun. Survivor.io drops you into a city swarmed by infected crowds, with giant bosses pushing through the streets and no backup in sight. One fighter stands between the outbreak and total collapse. Before the fighting begins, you pick a weapon that changes your early range and rhythm, from a katana for close slashes to a double-barreled shotgun for heavy blasts. Fallen enemies leave behind useful resources, which bulk up your loadout during the run. Coins from each fight raise your damage and toughness, so later waves don't shred you as fast.

How to play?

Choose one of three upgrades whenever you level up, then stack fresh attack options that fire alongside your main weapon. Homing missiles, burning bottles, and a map-wide blast add crowd control, boss damage, or full-screen cleanup when the swarm gets too thick. Dodging shots, staying out of the zombie pack, grabbing food for an instant heal, and opening chests or the fortune wheel all feed longer runs and higher records.
