I’m the developer of Damn, Zombies: The Corporate Undead, a solo or 1–4-player online co-op zombie FPS. The downloadable beta is available for Windows, macOS and Linux.

Survive escalating rounds in an office compound: repair barricades, buy weapons and open new areas. Managers strengthen nearby zombies, HR spawns more enemies, and co-op squads can split up to cover different entrances.

FREE ACCESS: SEVEN DAYS FROM FIRST KEY USE, EXTENDABLE ON REQUEST.

A free website account and activation key are required for public beta access. Internet is required, including solo play. Request an extension from your account page if you need more time.

Planned release: late October 2026; the exact day is unannounced and the Steam page is not live yet.

For transparency, the game uses AI-generated models, some audio/animation and development assistance. If you try the beta, I’d welcome feedback on the opening rounds, barricade pressure and joining friends.

Actual gameplay: the service yard is overrun.
