What is a Doomtrooper?

A Doomtrooper is an elite soldier chosen from the five mega-corporations that now run the Solar System. A Doomtrooper upholds all that is noble and respected in all the major corporations. They are usually war heros or people who have stood out in their military service to a corporation. In the single player game it won’t matter which corporation you belong to because the missions will all be the same. But in multiplayer when players choose teams, by choosing different colors, they are actually choosing different corporate alliegances.
