About This Game
Zombie Lab is a free-to-play first-person zombie shooter you can play directly in your browser. Armed with a flashlight-equipped weapon, you must navigate through pitch-dark research facilities and fight your way through hordes of the undead. With 10 unique stages — from abandoned laboratories and ruined city streets to underground subways and military bases — each environment brings new challenges and terrifying encounters.
Choose from 5 distinct weapons including a Pistol, Shotgun, SMG, Rocket Launcher, and Grenades, each upgradeable to level 10 for up to 2x damage and 0.55x reload speed. Face 6 types of zombies with unique behaviors: fast-moving Runners, heavily armored Tanks with 150 HP, acid-spitting Spitters, self-destructing Exploders dealing 60 explosive damage, and ground-crawling Crawlers. Every 10th level features an epic boss battle with special abilities.
Built with Three.js for immersive 3D graphics, Zombie Lab features realistic PBR lighting, real-time shadows, and atmospheric effects. The flashlight-only gameplay creates intense horror atmosphere where every dark corner could hide a threat. With 3 difficulty modes, a coin-based economy, and a full weapon shop system, there's plenty of depth to keep you coming back.
