Experiment No. 231

In this experiment, you need to leave the contaminated zone. Shoot the zombies, but keep an eye on your ammo; you can find more on the map if you run out. Also, monitor your pulse – the slower your heartbeat, the more likely you are turning into a zombie. There are first aid kits on the map that will help you survive longer. Zombies are very strong, so be cautious. The experiment begins!
