Future Wars

In 1989, an ordinary window cleaner is working on the facade of a skyscraper. While trying to play a prank on his angry boss, this unlikely hero discovers a secret passage leading to a time machine and mysterious alien documents. By operating the device, the protagonist is transported 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 it than that. The first installment in a planned series of time-travel games, though no further games were released.
