Codedoor

Codedoor is a survival action game set in an abandoned container yard overrun by zombies. Each session places you in an industrial landscape of locked containers. You receive a code and must find the one container that matches it and unlock it to advance to the next wave.

Search the container yard

Codes and containers are freshly generated for each session, creating randomized runs suited to speedrunning. The yard is designed with a detailed, atmospheric environment, and it holds rare and mysterious events.

Fight the waves

You use weapons such as the precise M1911 and rapid-fire MAC-10 to fight waves of aggressive zombies. The combat features weapon handling, visual kill effects and audio feedback, while survival under constant pressure tests your tactical thinking.

Reach the final wave

Your goal is to reach Wave 10 and secure at least 30 kills to unlock the Nuke. You can then pick it up and launch it to end the run.
