Mission Briefing:
Our scientists deciphered the ancient manuscript. It says that there is an artifact which can cure zombies. This is our last hope, humanity\'s last desperate attempt to recover from disastrous pandemia. Your mission: find this artifact in the ancient temple and activate it. Be aware: long range scans of that place show nasty deathtraps and hideous mutants. Going there is practically a suicide, but we don\'t have any other choice, so prepare yourself well.
