Outwars is a military science fiction selectable perspective tactical shooter developed by SingleTrac and published by Microsoft in 1998.

In single-player mode, wearing a choice of rocket propelled powered armors (Light Scout, Medium Combat, Heavy Assault, or Heavy Dreadnaut), the player controls a heavily armed, male or female member of the elite CDF Marine Jump Corps and must battle insectoid aliens (occasionally referred to as "The Skulls") intent on taking over the galaxy.

[3] Weapons and gear are gradually unlocked as play progresses, like the glider-wing which attaches to the rocket pack and permits extended aerial maneuvers when it is deployed.

The player's team is sent to grab all supplies from Oasis (in a return to the jump training mission) and prepare the jumpship for evacuation.

Right after the player escapes, Oasis is annihilated by some form of alien technology, and, in Hackett's words, "Have turned it into some kind of planet from hell".

The humans plan a last-ditch attempt to destroy 'The Skulls', but their first priority is to secure Planet Anubis, where the miners have discovered something in the mine shafts.

The player soon discovers that 'The Skulls' were living underground, but sick and tired of constant threat by the miners, they set out to eradicate all humans from existence.

They unfortunately find out, however, that Oasis (now known as DeadWorld) has been established as 'The Skulls' main base of operations, and they are set to beat the humans once and for all by eradicating their home - Earth.

"[15] Next Generation gave a negative review of the game, citing severe technical issues; from clipping to AI that add up to an overall bad experience.
