Future Wars

In 1989, an ordinary window cleaner is working on the exterior of a skyscraper. While trying to play a prank on his angry boss, the unexpected hero discovers a secret passage that leads to a time machine and mysterious alien documents. Operating the machine transports the protagonist to the year 1304, where he is given the seemingly ordinary task of rescuing a damsel in distress. But he soon discovers that there is much more to the story than meets the eye. The first installment in a planned series of time-travel games—though no further games in this series were ever released.
