Corridor Z

This will be the first trophy most people get (save for those following the walkthrough in the Roadmap found in this guide).

Being bitten by zombies will end your run, and is a perfectly natural thing to happen in this game. Being an endless runner, it may technically be possible to keep going without being bitten, but the game does get quite intense at around 4000+ meters, so eventually the zombies will come for all of us. When they finally do catch you after the tutorial you will be awarded with this trophy.
