LifeAfter: Night falls

Game description:

The entire world is in great danger and it seems that the era of apocalypse has just started. This time, the dwellers of our planet will witness something even more blood-chilling than zombies, vampires, or evil aliens. Their enemy is killing and cannot be seen anyhow. Yes, this is an invisible killer, something that sneaks inside of your body and stays unnoticed before you actually realize that you are dying. A virus. The planet turned into a real hell. The infection is becoming larger and spreads itself all over the planet. How long will stand such a catastrophe?
