Sherry’s Hiding Sequence (Claire A/Leon B)
The sewers section where you control Sherry has no combat and no inventory carry-over. Players circle the same rooms hunting for the next trigger. The exit: push the wooden crate near the waterfall room to create a stepping platform, climb up, and interact with the control panel to drain the water. The crate has no visual tell that it moves. If you’ve wandered more than five minutes, you missed it.
Valve Handle Puzzle (Water Purification Room)
Both scenarios require you to place valve handles on specific pipes to redirect steam and unlock the exit. The handles are scattered across multiple rooms, and the game never tells you which pipes are correct. Brute-force every combination or follow this: place handles on the pipes that visibly connect to the locked door’s mechanism. Check your map—rooms you haven’t fully explored show red; cleared rooms show blue. Missing a handle means backtracking to red zones.
G-Type 3 Boss (Sewers, Both Scenarios)
William Birkin’s third form has a one-hit-kill grab that ends runs. Players waste all their Magnum rounds trying to burn him down and die during the forced climbing sequence immediately after. The unblock: ignore the boss. Sprint in circles around the arena’s outer edge until the timer expires (roughly 90 seconds). He roars, the exit opens, you climb. Save your Magnum rounds for G-Type 4 and G-Type 5. If you already dumped your ammo, reload an earlier save—there’s no recovery path.
Laboratory Self-Destruct (Final 10 Minutes)
The timed escape gives you five minutes to navigate four floors with respawning enemies and a final boss. Players panic and fight everything. The optimal route: ignore all enemies, take the central elevator down, grab the platform key from the save room (if you didn’t already), activate the train, fight the final Tyrant with everything you saved. Stopping to shoot zombies during the countdown wastes time you don’t have. Ink Ribbons are in the save room—use one before the escape starts.
