Babylon Hotel

Talk to the desk clerk in the Lobby to get a room, but don't head up yet. On the 2F Hall, search a room door once to see its number and again to enter — visit 203 and 206 and remember where they are. On 3F, visit 304 and 303 first (the man inside 303 kicks you out twice before you can just walk back in), then finally head to your own room, 302.

Entering 302 triggers an FMV; search the bathroom mirror, then head to 306 (he'll kick you out once — walk right back in). Talk to him, grab the Delemetor and Recovery Capsule on either side of the room. Back in the Lobby, go behind the counter and through the door on the right into the Employee Lounge — grab the Recovery Capsule, but don't flip the circuit breaker yet. The guest from 306 will be waiting outside after — talk to him, then head to 204.

Talk to the man in 204 repeatedly — he'll teach you a door-knock pattern and eventually send you to room 201. Grab the Skip and Appolinar here if you have room; leave the rest of the drugs if your pouch is full. When you try to leave, he gives you the D-Felon directly — inject it manually if you have space, since it's stronger than letting the game force it into your last free slot.

Back at the Lobby, the door beside the save room reveals the man from 306 — dead. Hurry to 201: recovery capsules on both sides as you enter, Delemetor on the bed, talk to him, then head to 304. Leave and immediately walk back in to trigger a scene, take the Nalcon and Recovery Capsule in the corners, and the bellboy outside sends you to 301.

Clear the two Rabbits in suits in 301 — tight quarters make this harder than it looks — and search the desk for the Letter from Lilia. From here on, someone new is dead every time you backtrack: 304 is empty when you return, so move on to 303.

Talk in 303, then go to 205: pick up the phone and grab the Nalcon on the desk. Back at 303, he's dead too — go to 206, talk, and take the two Recovery Capsules. Go to 202 and kill the single Rabbit in a suit, then return to 206 — dead as well. Go to 203, talk one last time, then head to 305, where three Rabbits in suits are waiting. Clear them, then check back on 203 — dead, like the rest.

Head back to the clock on the 2F Hall for an FMV — Rainheart teleports away toward 3F. Save first if you can, then follow him up. He teleports into 305 just as you arrive; go in for the fight.

Room 204 is empty when you return for leftover drugs — the last guest, from 201, is the only one still alive, back in the Lobby. He's already pulled the warning tape off the boiler entrance. Save first, then flip the circuit breaker in the Employee Lounge — this permanently disables the save terminal, so make sure you're ready before you do. Head down into the Boiler Room (2x Arabesque — the hotel's power being off is what let the elevator here activate, so there's no avoiding them).

In the Kitchen, head into the bathroom first — an Arabesque appears behind you once you leave it, so don't backtrack unnecessarily. In the Bathroom, grab Red from the right wall, Skip from the toilet, and a Recovery Capsule from the far wall. Ignore the Arabesque waiting outside on your way to the Dining Area.
