Survive as many rounds as you can: every round brings more zombies, and faster. Six maps — Bunker, Factory, a night-time Town, San Rafael Hospital, Fort Reyes, and an underground Lab — plus a shooting range to try every weapon.
The story mode, Operation Lazarus, runs across six chapters with a squad mate, 13 cutscenes, 250+ voiced lines with subtitles, and a final boss. Online co-op for two players runs peer-to-peer over ENet (UDP), with the host as the authority so zombies, rounds, and damage never desync.
No engine underneath: rendering (PBR shaders, shadow maps, HDR + bloom), physics (ragdolls, pushable props, explosions with shockwaves), AI, audio, and networking are all written by hand in C++.
