Day 2 Warehouse Rats — The sewer beneath the warehouse throws waves of mutant rats at Aya while she’s still carrying the starting M93R pistol. The rats move fast, stun-lock on contact, and respawn until you reach the exit ladder. Don’t fight them all. Equip the Firefly armor (police station locker room, Day 1) for poison resistance, then sprint straight through the flooded corridors. If you must engage, switch to the P08 handgun for faster fire rate and keep moving laterally — standing still gets you swarmed.
Day 3 Museum T-Rex — The Tyrannosaurus boss has a deceptive hitbox and one-shots underleveled Ayas with its charge. The arena is circular with pillars; use them. Bait the charge, sidestep behind a column, then unload into the flank while it recovers. Don’t waste Parasite Energy on offensive spells — save PE for Healing and keep distance. If you sold the Mongoose rifle to the weapon trader earlier, you’re stuck with the M93R; aim for the head during its roar animation for critical damage windows.
Day 4 Subway Alligator Gauntlet — The flooded subway tunnels force Aya through narrow corridors with mutant gators that inflict Poison and Darkness status. Players often run out of Medicine between safe rooms. Backtrack to the ticket booth save point and stock up before descending. Equip the N-Spader armor (dropped by the Centipede boss on Day 3) for Poison immunity. Use the MP5A5 submachine gun’s spread to hit multiple gators in tight spaces. Don’t waste inventory slots on Antidotes if you have N-Spader equipped.
Day 5 Statue Puzzle — The Statue Hall requires pushing four angel statues onto pressure plates in a specific order, but the game gives zero feedback when you’re wrong. The correct sequence cite: North, East, South, West (clockwise from the entrance door). If statues won’t budge, you’ve already placed one incorrectly — reset by leaving the room entirely and re-entering. The statues lock in place once correct, so you can’t accidentally undo progress.
