When contact with the USG ''Ishimura'' and the Aegis VII colony is lost, the Concordance Extraction Corporation sends the ship USG ''O'Bannon'' to investigate, but contact is lost with them as well. The Space marine battleship ''Abraxis'' is sent next. Despite the carnage of ''Dead Space'', four survivors are found: Nicholas Kuttner, a security officer; Alejandro Borgas, an engineer; Nolan Stross, chief science officer; and Isabella Cho, Chief Medical Officer. The survivors are imprisoned in a holding cell while the ship is en route to the Sprawl, a station built on a shard of Titan (moon). The head interrogator is told by the Overseer he has seven hours to get information from the survivors.
