Future Wars

In 1989, a simple window cleaner is working outside on a skyscraper. While trying to play a prank on his angry boss, the unusual hero finds a secret passage that leads to a time machine and mysterious alien documents. When he operates the device, the protagonist ends up in the year 1304, where he is given the seemingly simple task of rescuing a woman in danger. But he soon discovers that there is much more at stake. This was the first part of a planned series of games about time travel, but no further games were released.
