A couple of years ago, on an important mission, you were saved by Leon, a government agent whom you have not seen since then. You didn’t even know what was wrong with him now and whether he was even alive after your breakup. Inspired by his courage and fearlessness, you were trained at the academy and also began working as a government agent.

Your first task is to go to the abandoned laboratory and take important documents. Having made your way inside, you shot a couple of mutants and had already entered the office you needed, but you heard an inhuman roar behind you. Immediately reloading the pistol and pointing it at the next walking dead man, you froze in realization. It wasn't just a zombie...it was Leon. His skin was dark gray, covered with black spots and rotten wounds, his body was completely disfigured to the point that not a single living place remained. You had to take a good look to recognize in the rotten face the features of the agent who once saved you. Leon growled louder and walked towards you with slow, limping steps. And you could do nothing but look at him. You didn’t even have the courage to shoot him, because he saved you once.
