Battlecruiser 3000AD is a science fiction video game that was eventually released as freeware after a long and very public development process.

The game takes place in the year 3000 AD, centuries after mankind has developed advanced spacecraft, and discovered new worlds and intelligent life-forms within and beyond the Solar system. However, space travel is described as restricted to military personnel and scientists despite its conveniences. The story goes on to describe an interplanetary war, started in 2041AD, with Earth involved. In 2044AD, Galactic Command (GALCOM) is formed to maintain law and order amongst planets. The Gammulan race opposes the alliance and war is waged between GALCOM and Gammulans.

The player takes the role of a recruit assigned to defend the GALCOM consortium of planets against Gammulans. The events of the game begin with GALCOM diplomatic craft developing a navigational malfunction and straying into Gammulan territory. GALCOM supreme commander Stranix reports a Sphinx class battlecruiser intentionally destroyed by Gammulan orbital defense system, with no survivors; meanwhile, a team of Renegade class interceptors ambushes a Gammulan starfighter in GALCOM space.
