The world is desolated and stinted. The earth’s surface has been radiated and is now uninhabitable. The unteachable human race caused WW3… and it was a nuclear war. All life has vanished.
Survivors seek protection and food and fight for survival every day. Chaos and anarchy rule the world. In small groups everyone now fights for themselves and is on their own.
Whilst searching for food you (guys) stumble upon an old abandoned military bunker. Does it still have food? Inquisitively you go in deeper into the bunker. Dammit! The door is blocked!
The oxygen in this room will last for only 60 minutes at most… You really need to hurry now if you don’t want to take your final breath right here….
