Cryptrover: Escape from the Crypt

You are an archaeologist trapped in an underground crypt with a limited supply of air. You must survive long enough to reach the crypts exit.
- Be too rash - and the arachnids will nibble you to death.
- Be too wary - and your air supply will run out.
Luckily, the ancients have left behind med packs, air cans and batteries in the crypt - try not to waste then in vain!
