Travel to the future and save humanity from extinction!

In the year 2076, our planet is on the verge of collapse. The last redoubts of civilization live hidden in underground shelters, since on the surface the lack of oxygen has erased all traces of life except for the AFL, anaerobic mutant beings that have become the new dominant species.

Professor Marcus Tesla is a renowned scientist who tries to change the destiny of the planet, investigating a way to regenerate oxygen and end the AFL.

However, after some last hopeful advances in his investigation, we have lost all contact with him...

Your mission is to enter bunker BK-437, where the professor's laboratory is located, and try to find any clues about his whereabouts or his research.
