Survival horror prequel where you control two characters—Rebecca Chambers and ex-Marine Billy Coen—switching between them to solve puzzles and fight zombies. The partner system means you're managing two inventories and using each character's skills to progress through an abandoned train and research facility. You can drop items anywhere instead of relying on storage boxes, which changes how you plan resource use. Enemies include standard undead plus new creatures like a mutant centipede boss. Combat uses fixed camera angles and tank controls typical of early Resident Evil games. Puzzles require coordinating both characters, sometimes splitting them up to cover more ground. Expect limited ammo, backtracking, and tense encounters in tight corridors. Good fit for fans of classic survival horror who want more backstory on Umbrella Corporation's experiments.
