Hold the line as the swarm closes in until the screen is mostly zombies and muzzle flash. Chunky 3D models and heavy-hitting effects give every wave real weight.
Editor's take
Grand Zombie Swarm earns its title — this is crowd horror, where the threat is not one zombie but the texture of hundreds pressing toward your barrel. Ammunition economics carry the game: every magazine becomes a budgeting decision, every reload a calculated risk. The 3D arenas give the horde room to flank, which punishes static play exactly as it should. Waves escalate from stroll to siege at a fair clip, and the between-wave shop arrives just often enough to matter. As a pure power-fantasy shooter it over-delivers for the format, and the swarm rendering holds up impressively in a browser tab. A dependable Friday-night catharsis. Bring a spare mouse; you will need the clicking endurance this horde demands.
