Resident Evil 0 is Capcom’s 2002 survival horror prequel. It sends rookie S.T.A.R.S. medic Rebecca Chambers onto a train full of corpses the night before the original game’s mansion incident. The fear comes from a slow squeeze: fixed camera angles that hide what’s around the corner, no item boxes, and a carpet of shrieking leeches that never seems to end.
Story and setting
It’s July 23, 1998, in the Arklay Mountains outside Raccoon City. Your helicopter, carrying S.T.A.R.S. Bravo Team, makes an emergency landing in the forest. While searching the area you find two things. One is an overturned military police truck with its escort dead. The other is the Ecliptic Express, a luxury train sitting idle on the tracks with every passenger dead or something worse.
You play as Rebecca Chambers, an 18-year-old field medic on her first real mission. She’s soon forced into an uneasy alliance with Billy Coen. He’s a former Marine lieutenant sentenced to death for murder, and he walked away from that wrecked truck. Rebecca wants to arrest him. Billy wants to survive the night. Neither gets much choice, because whatever killed the passengers is still aboard.
The train is only the opening act. The campaign moves into an abandoned Umbrella training facility, a grand, decaying building with portraits and trophy rooms. It feels like the Spencer Mansion’s older, stranger cousin. Running through all of it is a man in white who sings to the leeches as if they were his children.
How it scares you
Two characters, one bag problem
The signature mechanic is partner zapping. You control Rebecca and Billy together and swap between them with a button press, either moving as a pair or splitting up. Their skills differ:
- Rebecca mixes herbs and chemicals, squeezes through small gaps, and takes damage badly.
- Billy hits harder, shrugs off more punishment, and handles heavy lifting such as pushing crates and moving obstacles.
Splitting them up is where the dread lives. A puzzle might strand Rebecca alone in a dark room while Billy sits two floors away holding the shotgun. You hear her scream over the radio and realize the help you need is a long walk off.
No item boxes
Every other classic Resident Evil gives you magic storage chests that share contents across the map. Zero removes them. Each character carries six slots. Anything else, from spare ammo and herbs to key items, has to be dropped on the floor and remembered. The map marks dropped items, but you still have to walk back for them through corridors you thought you’d cleared.
This change splits fans. Some love the logistics. Others find the backtracking a chore, especially with the hookshot, which is a notorious slot hog. Either way, it creates the tension of always holding the wrong thing when something lunges at you.
Enemies and pacing
Zombies are the backbone, and they hit hard. The train and facility also throw in leech men, Eliminators (infected baboons that leap at you from awkward angles), Hunters, giant frogs called Lurkers that can swallow a character whole, and some proper spectacle bosses. Ammo runs tight on your first run. You’ll learn to dodge around enemies instead of killing everything in sight.
The pacing is front-loaded. The train is a near-perfect horror setpiece: cramped, rocking, rain lashing the windows. The second half leans heavier on puzzles and item shuffling, so the scares thin out as the run goes on.
Camera and sound
Zero uses pre-rendered backgrounds with fixed camera angles, the last time Capcom built a mainline entry this way. The camera decides what you see. A groan from off-screen, or a shuffle just beyond the frame, does more work than any monster model.
The sound design deserves its own credit. The wet squelch of leeches gathering into a person-shaped mass is one of the series’ grossest noises. The facility’s ambient score is quietly excellent.
Lore and ending
Spoiler warning
This section spoils the ending, the villain’s identity and Billy’s fate.
The singing man is Dr. James Marcus, one of Umbrella’s founders alongside Oswell E. Spencer and Lord Ozwell E. Spencer’s partner Edward Ashford. Marcus developed the t-Virus by splicing a progenitor virus with leech DNA. In 1988, Spencer ordered his assassination, and two of Marcus’s own students carried it out: Albert Wesker and William Birkin. Zero lets you watch them now, scheming in a surveillance room.
Marcus didn’t stay dead. His favorite leech, the Queen Leech, absorbed his body and memories. Ten years later it takes his form and unleashes the infestation on the Ecliptic Express as revenge on Umbrella. Rebecca and Billy fight it down to the facility’s treatment plant. In the final battle they drag it into the sunlight as a self-destruct sequence wipes out the site.
There’s only one ending. As dawn breaks, Rebecca takes Billy’s dog tags and tells him that, as far as her report goes, Lieutenant Billy Coen is dead. Earlier he explained that he was framed for a botched mission in Africa, and she believes him. He walks into the forest. She turns toward a mansion visible through the trees, which leads directly into the original Resident Evil.
The lore payoff is mostly about Wesker. Zero confirms he was already plotting against Umbrella before 1998. It also confirms he chose S.T.A.R.S. as test subjects for the mansion’s bioweapons on purpose. Birkin’s obsession with his own research, the G-Virus behind Resident Evil 2, is seeded here as well. Billy’s story stays open; he hasn’t returned in a mainline game.
Where it fits in the series
Zero is the first game in story order, but it arrived after the original trilogy and Code: Veronica. It began life as a Nintendo 64 project and moved to GameCube during development, launching that November. Koji Oda directed. Capcom’s GameCube remake of Resident Evil came out earlier in 2002, and the two games share an engine and a look.
| Release order | Year | Story order |
|---|---|---|
| Resident Evil | 1996 | Resident Evil 0 (July 1998) |
| Resident Evil 2 | 1998 | Resident Evil (July 1998) |
| Resident Evil 3: Nemesis | 1999 | Resident Evil 3 (Sept 1998) |
| Code: Veronica | 2000 | Resident Evil 2 (Sept 1998) |
| Resident Evil 0 | 2002 | Code: Veronica (Dec 1998) |
The versions you’ll come across:
- GameCube original (2002): the source, now a pricey collectible.
- Wii port (2008-09): the same game with Wii Remote control options.
- HD Remaster (2016): released on PC, PS3, PS4, Xbox 360 and Xbox One. It adds rebuilt backgrounds, a widescreen option, modern analog controls next to the classic tank controls, and Wesker Mode, which swaps Billy out for a very overpowered Wesker. It was also bundled with the Resident Evil HD Remaster as the Origins Collection.
- Switch (2019): the HD Remaster on Nintendo’s hybrid.
Play the HD Remaster. It’s the most widely available version, and modern controls take the edge off the item juggling.
On order, our position is to play the Resident Evil remake first, even though Zero takes place earlier. Zero’s reveals about Wesker and Marcus land much harder once you know what happens in that mansion. That’s how players met them in 2002.
Where to play
As of October 2026, Resident Evil 0 HD Remaster is available on:
- PC via Steam
- PlayStation 4, playable on PS5 through backward compatibility
- Xbox One, playable on Xbox Series X|S through backward compatibility
- Nintendo Switch, digitally on the eShop
The PS3 and Xbox 360 digital versions still exist for people who already own them. Capcom is the publisher everywhere, and it discounts the game deeply and often during seasonal sales. Wait for one if you aren’t in a hurry.
As of October 2026, don’t plan around Game Pass or PS Plus. Zero has never been a dependable part of either catalog. Check the current listing before you subscribe for it, but expect to buy it outright.
On Steam Deck, the remaster runs well in our experience. It’s a 2016 game built on 2002 foundations, so performance is not a concern. Check the compatibility icon on the store page for Valve’s current rating.
Switch 2 owners in the Resident Evil mood should know that Resident Evil 2, 3 and 4 reach Switch 2 October 16. Review copies of those remakes show mixed performance, so read up before you choose that version.

FAQ
Is Resident Evil 0 a prequel?
Yes. It takes place on July 23, 1998, the day before the original Resident Evil, and follows Bravo Team medic Rebecca Chambers. It’s the earliest game in the series’ story order.
Should I play Resident Evil 0 or the Resident Evil remake first?
Play the remake first. Zero was made for players who already knew Wesker and the mansion. Its lore reveals and final shot hit harder with that context.
How long is Resident Evil 0?
Expect about 9 hours for the main story on a first run. Speedrunners finish in a fraction of that. Completionists who go after Leech Hunter and Wesker Mode will add several more hours.
Is Resident Evil 0 hard?
It’s one of the tougher classic entries because there are no item boxes, so poor inventory planning punishes you. Easy mode and the HD Remaster’s modern controls help a lot if you’re new to fixed-camera games.
Is there a Resident Evil 0 remake?
Capcom hasn’t confirmed a full remake at the time of writing. Rumors have come from insiders with mixed track records, so treat them as unconfirmed. For now, the 2016 HD Remaster is the version to play.
