- — Rooker in "Relentless"
Rooker was the radioman of the Marine Raiders rescue team led by Sgt. Tom Sullivan and Cpl. Roebuck, which made a raid on Makin and saved Pvt. C. Miller. Later during the assault, the squad find a bunch of "dead" Imperial Japanese soldiers in the jungle. Sergeant Sullivan told Rooker to call another squad with his radio, in order to check if they already cleared that area.
When Rooker was going to use his radio, a signal flare rose, blinding everyone. Rooker was then stabbed by a Japanese soldier wielding a katana. His "body" was left behind in the ensuring chaos. Despite this he later returns in Relentless where he assists in clearing out the caves towards the end of the level, apparently having been promoted to the rank of Sergeant in his time away.
