About this game

Grand Zombie Swarm is an open‑world shooting game where you play as a special‑forces soldier tasked with surviving waves of undead. Using the WASD keys to move, you can pick up a range of firearms and clear each level of zombie hordes, aiming with the right mouse button and switching weapons with the mouse wheel. Each level is a self‑contained arena within a larger city map, encouraging you to explore, find ammo caches, and plan your next ambush.

The game feels fast‑paced and rewarding thanks to the variety of guns and the need to manage reloads and jumps while staying alive. The 3D Unity engine delivers smooth combat visuals, and blood effects add extra impact to every shot. It runs in any modern browser via WebGL, is completely free, and works on desktop and mobile devices without any download.
