Detailed walkthrough for Resident Evil, covering the Mansion section. Learn how to defeat zombies, find key items like the shotgun and map, and progress through the early stages of the game.

Walkthrough
  1. 1
    After speaking with Barry, proceed through the far door to encounter your first zombie. Shoot it until it falls, then shoot it again to kill it. Collect the clips.
  2. 2
    Return to Barry. A zombie will burst in; Barry will handle it. Proceed to the Main Hall.
  3. 3
    Barry gives you a lock pick. Go through the blue doors. Move the steps to collect the map, then move the desk to access another room. Kill the zombie on the floor, collect the ribbon, and exit.
  4. 4
    Go through the other door. Shoot the two dogs that burst through the window.
  5. 5
    Continue down the corridor. The first door is a bathroom (ignore unless Chris, then drain water for a cabinet key).
  6. 6
    Proceed to two more doors. The left door contains the shotgun (Jill only; Barry saves you from a trap). Do not enter if Chris.
  7. 7
    Go through the other door to face two more zombies. Aim high for headshots if Jill.
  8. 8
    Enter the Grey Door, kill the zombie by the stairs, collect the green plant, and enter the save room. Save your game, collect the Earth, and exit.
  9. 9
    Go upstairs. Kill the zombie to your left and the one behind you. Enter the door at the end of the corridor.
  10. 10
    Shoot the zombie and enter the small study. Examine the Botany book and leave.
  11. 11
    Continue down the corridor, past the green doors you cannot enter yet. Shoot another zombie.
  12. 12
    Enter the unlocked door, returning to the Main Hall. Barry (Jill only) gives you bazooka ammo.
  13. 13
    Find the bazooka in the door next to the one you just exited, guarded by crows. Collect it (Chris gets clips). Do not kill the crows.
  14. 14
    Exit and go across the hall to the other door. You are now on the balcony above the Dining Room. Kill the two zombies.
  15. 15
    Push the stone statue off the balcony and go through the far door. Kill the two zombies by the stairs and go down.
  16. 16
    Kill the two zombies at the bottom of the stairs and go through the door. If Chris, you meet Rebecca; agree to her help for later benefits. Collect the ribbon (Chris gets a key) and save.
  17. 17
    Exit and continue down the corridor, encountering another zombie.
  18. 18
    The door on your right contains items (clip, shotgun shells, rusty shotgun for Chris). You cannot enter yet.
  19. 19
    Go through the other door, shoot the zombies, and head down the narrow corridor towards the plant room.
  20. 20
    In the plant room, put the Earth in the pump to kill the plant and collect the key behind it. Use green plants if injured.
  21. 21
    Return to the rusty shotgun room and collect the items (Chris uses the rusty shotgun to get the regular shotgun).
  22. 22
    Go back through the doors and turn right.
  23. 23
    Enter the door on your right to find a bedroom. Collect the clip on the bed. A zombie will emerge from the cupboard when you investigate the desk.
Tips
  • Aim for the head when shooting zombies to conserve ammo and potentially kill them faster.
  • If playing as Jill, the shotgun is a valuable early weapon.
  • Conserve your ammunition, especially early on. Use the knife for weaker enemies if comfortable.
  • Remember the save room locations and use them strategically.
  • If playing as Chris, accepting Rebecca's help can be beneficial later in the game.
