Mars, 2044. The UN establishes MARSCORP (Martian Security and Economics Committee) under the leadership of Samuel Longwood. In the years that follow, the UN gradually loses control of MARSCORP, mainly due to the non-transparent licence policy of its director. Longwood uses his autonomous status to create vassal relations between the corporations and MARSCORP. The unshakable power position of MARSCORP is supported by the companies and thus they acquire additional rights and licenses. Longwood and his consortium become extremely wealthy from this arrangement. However, dissenting voices in MARSCORP begin to challenge Samuel Longwood's authoritarian policy. They demand his dismissal as director and a complete redistribution of the mining rights.

But Samuel Longwood keeps an ace up his sleeve for occasions like this.

Chaser awakens on board the spaceship H.M.S. Majestic. He doesn't know who he is, what he's doing here, why he is being sought by men in black uniforms and what they will do to him when they find him.

The player's goal is to find out who Chaser really is and why he is being hunted. The story leads the player from the H.M.S. Majestic to Montack City on Earth, then on to Siberia and finally to Mars, where the trail ends and hopefully the truth can be found.
