Part 40

Sadist Encounter: Gather all items, then kick the barrel into the Sadist's room. Use Freeze Bolts, Explosive Bolts, and the two barrels to defeat the Sadist. Collect the key and proceed.

Sentinel Boss Fight: This fight features Sentinel with increased health and many new bear traps in the arena, especially in the middle and near shotgun shells. Beware of grassy sections, which are particularly dangerous on AKUMU mode.

Sentinel Strategy: Use Electric Bolts to stun Sentinel, then follow up with shotgun blasts or grenades. Circle around Sentinel to avoid his charge and land free hits. On AKUMU mode, focus on knocking him down and dealing damage quickly. Approximately 2-3 explosions and 6-8 shotgun blasts will defeat Sentinel.

Chapter 7: The Keeper (Tips): This chapter is relatively straightforward. Kill enemies in the hallway, using the bomb by the tomb if desired. Save your progress and use keys in the lithograph puzzle room.

Chapter 7 - Left Path: Snipe the two-head enemies to disarm bombs. In the gas area, move quickly to kill the enemy and turn the two valves. Use the bomb in the tunnel against the two-heads or try to outrun them.

Chapter 7 - Right Path: After grabbing the key by the lever, run to the wire, disarm it, and shoot the gears to stop an incoming rolling trap (Nightmare Mode only). Kill the two-head on the spikes. In the next room, burn the two-head by the tunnel. Use the trap in the room to kill monsters. Disarm traps in the gas room to get the third key. Outrun the appearing two-head.

Chapter 7 - Final Keeper Fight: Kill the two-heads in the pit and by the lithograph manually to get the fourth key. Head back to save. The Keeper fight is not difficult. Two rifle shots should be enough to kill him. Kill him once, collect items, and hit the lever. Run to the door, hit the next lever, and kill him a second time. Run to the exit room, get the lever, freeze him as he follows, and escape.

Chapter 8: A Planted Seed Will Grow (Tips): This chapter is easier. Snipe the first few two-head enemies and use head pistol shots. Kill the two-headed foes in the lever room and get the key. In the baby room, running over babies kills them instantly.

Chapter 8 - AKUMU Mode: Lay an electric trap by the door before opening it. As babies fall, stop opening the door and run around to squish them, using the electric trap for any missed enemies.

Chapter 8 - Progression: Continue to the waterfall for the second key, then run through the trap room. Get the third key from the pipe and proceed to the end of the chapter.

Chapter 9: The Cruelest Intentions (Tips): This section begins the approach to the Mansion, hinting at increased difficulty.
