The fourth unit of the expansion Ground Zero.
The Gravity Well is closed, yet a device of such magnitude cannot be destroyed by conventional means. High Command has decided that an Antimatter Bomb is the best way to complete the mission, and therefore Stepchild is sent to a major Strogg munitions plant to obtain one.
However, such powerful weapons are not just sitting around, waiting to be picked up. The marine will have to create the bomb's antimatter core and containment pod, and then unite them, using the available Strogg equipment.
Once he is ready he can take the gondolla into the Gravity Well complex.
