Resident Evil 0
The S.T.A.R.S. Bravo Team was dispatched to the Arklay Mountains to investigate murders that have occurred within the area. Upon their arrival, their helicopter crashes. The team survives the crash and comes across a wrecked military transport vehicle. They found out that ex-marine Billy Coen, now a murderer, was being transferred to death row for execution until the transport came under attack by an unknown enemy. The soldiers that were guarding Coen as mauled to death and Coen was nowhere to be found. The team then splits up to find the escaped convict.
Rebecca is soon separated from her team and stumbles upon the Ecliptic Express which had stopped in the middle of the forest. She searches the train and finds out it is full of zombies and one has wounded her teammate, Edward Dewey. Soon after Rebecca is rescued from a zombie attack by Billy Coen. Coen suggests that the two team up for a better chance at survival. Rebecca agrees but plans on tuning Coen in when they reach safety. The train starts to move and brings them to an underground training facility set up by the Umbrella Corporation. While exploring the facility, Rebecca begins to trust Coen and asks why he was being sentenced to death. He informs her that he was accused of killing 23 villagers while on a mission but was innocent. Rebecca believes him and protest him from Bravo Team leader Enrico Marini, by lying about Billy's location. Unbeknownst to Rebecca and Billy, they were under surveillance by Umbrella Researcher, William Birkin and S.T.A.R.S. Alpha Team Captain, Albert Wesker.
After fighting through the underground facility, the two come across Dr. James Marcus, one of the founding members of Umbrella. James Marcus was murdered by his colleagues William Birkin and Albert Wesker, only to be resurrected by his genetically modified leeches (carriers of the T-Virus). Marcus now had the power to control the leeches mentally and was controlling them throughout the game. Unfortunately, due to the unstable T-Virus Marcus transforms into a Queen Leech right in front of their eyes. After defeating Marcus the two escapes the facility before it self-destructs. The two go their separate ways and Rebecca repots that Billy Coen was killed. Before separating she retrieved Billy's dog tags as proof. Billy flees into the forest and Rebecca heads to the Spencer Mansion to regroup with her fellow teammates.
Rebecca enters the Spencer Mansion but doesn't find her teammates. She then heads to a bedroom where she goes to sleep but is later awakened by a nightmare. At this time she sees her teammate, Richard Aiken, and together they explore the mansion but once again they are separated. Rebecca then proceeds to the main hall where she runs into Chris Redfield. The two moves on together. Rebecca doesn't really do much other than help with puzzle solving and playing the Moonlight Sonata to help open a passage. The duo soon finds Richard Aiken badly wounded after an encounter with a giant snake. Richard dies from the wounds and Chirs manages to defeat the snake.
Rebecca and Chris are then taken by Wesker who informs them that he set up everything in order to receive combat data, to see the Tyrant. When the Tyrant is released it turns on Wesker and supposedly kills him (or at least thats what everyone thought). Rebecca helps Chris in defeating the Tyrant and afterwards they free Jill Valentine. Jill and Rebecca must then hold off swarms of zombies while Chris signals Brad Vickers for a pickup.
While waiting for Brad, the Tyrant returns stronger than before. At this time the trio's weapons does little to nothing to defeat the beast. Brad throws down a rocket launcher which Chris uses to defeat the Tyrant once and for all. THe trio then climbs aboard the helicopter and escapes the facility before it is destroyed.
This game retells the story of Resident Evil 0 an the original Resident Evil. Once again Rebecca is teamed up with Billy Coen. After defeating James Marcus she is ordered to go to the Spencer Mansion to regroup with her fellow team members. She finds a safe room which she holes up in for some time. She witnesses Sergei Vladimir removing the U.M.F.-013 and the Ivans defeating the mutated hounds. Rebecca then falls asleep and has a nightmare about a giant snake called Yawn before she actually comes across it. She is then reunited with Bravo Team member Richard Aiken. The two fight their way throughout the mansion and soon come face to face with Yawn. THe two battle the snake in the library where Richard is fatally wounded by the Yawn, after saving Rebecca. The two are then saved by Chris Redfield and Jill Valentine. Richard dies there from his wounds.
