The Kellion crew arrives at the outskirts of Aegis VII, but they crash-land aboard the Ishimura due to a docking malfunction. An injured Johnston stays behind as Isaac, Kendra, Hammond, and Chen investigate the seemingly abandoned ship. Necromorphs made from the corpses of the Ishimura's crew attack the group, killing Chen and forcing them to separate. As they battle the undead crew, the trio split up to explore the ship and find out what caused the outbreak. The situation soon worsens when the Necromorphs damage the Kellion's singularity core, causing the ship to explode and kill Johnston, while Hammond is attacked by a mutated Chen while searching the ship's bridge. Unwilling to harm his friend, he seals Chen in an escape pod and jettisons him into space. Kendra accesses the Ishimura's central computer and discovers that the ship was harboring a "discovery" from Aegis VII.
