The story begins at Mikhal's World, which is under attack by "The Skulls". It has become overrun, and the humans are ordering an emergency evacuation. The player has 02:00 minutes to reach his ship or he is left behind. After this, the player is dropped onto Planet Oasis, where he goes into training. But while target training is underway, "The Skulls" attack, forcing an immediate evac from the area. War has broken out all over Oasis, with the humans losing badly. The players team are sent to grab all supplies from Oasis (In a return to the jump training mission) and prepare the jumpship for evac. Eventually, a total evacuation is ordered on Oasis, but the player is denied leave until he retrieves 'special technology' from the now abandoned military base on Oasis. 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. No survivors are found, but the player is sent to destroy the mine shafts and whatever may be in there. 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. But while moving through the mine shafts, the player falls deep into the Skulls lair. The player meets his first 'Queen' in this level, and after defeating it, the CDF find a way out for the player, and he is immediately evacuated. They prepare to send the players team onto the enemy's current stronghold, the Juggernaut, but are ambushed along the way. The Ulysses is shot down, and the player is dropped by accident onto Ragnarok. After meeting up with another survivor, the player is forced to take down the enemy's air gun that is keeping the CDF from rescuing the player and his current teammate. After it is destroyed, the player is sent to investigate the Ulysses to rescue Commander Hackett, retrieve the command data from him, and afterwards, assist the troops in a war at the ravine. It is decided that the Ulysses is too dangerous to be left standing, so the player is sent back to destroy it. Afterwards, the player leaves Ragnarok, and resumes the mission of destroying the Juggernaut. They first capture the Mastermind to find out the codes for the security locks on the Juggernaut, and after killing the second queen, the player rushes off the Juggernaut before it explodes. 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. A last-ditch attempt is thrown to disable their primary attack and turn it against them, ending the Skulls threat once and for all. The player manages to get inside the gun, and is given a limited amount of time before it fires. While disabling the gun, the player meets the boss of the game - The King, the largest monster in the game (approx. 4 times the height of the player). After defeating it, it turns out that he was the main control for the gun, and without him, the Skulls are doomed. The player reactivated the gun, but shoots himself out, seconds before the planet destroys itself. The player is then given one last message before the logo and credits: "Stay there, Captain. We're coming to get you."
Alternate scenes
If the player does not escape Mikhal's world in time, the planet blows up, but the dropship does not appear, indicating he didn't make it.
On Oasis, there is a mission where the player is told to blow the base reactors up. If he doesn't make it, the screen brightens extremely, and the player instantly collapses and disintegrates (Of all the scenes, this is not a cutscene, it is gameplay).
If the player does not escape the Juggernaut before it blows up, like the Mikhal's World scene, there is no dropship shown when it blows up.
If the player is killed by the King, or he runs out of time on the Final Mission on DeadWorld, a long cutscene is shown where the DeadWorld gun fires, and produces similar results as with Oasis/DeadWorld.
Reception
Pelit scored the game 90 out of 100 and summarized that "Don't let the bad graphics distract you from the excellent game underneath".
Next Generation reviewed the PC version of the game, rating it one star out of five, and stated that "steer clear of this nightmare in a box."
