How to unlock the That's Officer Chambers to You achievement in Resident Evil 0 - Definitive Guide

To win this achievement you need to defeat all the games boss monsters as Rebecca. This is with the exception of the centurion and the final boss, as you do not have the option of controlling Rebecca for these battles.

The boss's are:
The giant scorpion on the train, so have Billy reconnect power and fall through the roof.
The infected bat in the church.
The prototype tyrant.
The prototype tyrant round 2.
The Marcus leech thingy (first battle)
Leech Queen Phase 1 (just after getting off the lift and before Rebecca starts activating switches)

Boss's need to be killed in one single play-through. Whilst fighting the prototype tyrant for the second time and the Marcus leech thing, set Billy to idle or even disarm him, so that he doesn't accidentally get the killing shot, as this will void your achievement. Achievement should pop after the credits have finished rolling.
Good luck

The only bosses you need to worry about are:
Stinger (scorpion in train; have Billy restore power on top of the train);
Infected Bat (in the church; have Billy step on the pressure plate to open the door);
Proto-Tyrant 2nd Fight (in treatment plant; go down the elevator only with Rebecca);
Leech Queen 1st Fight (end of treatment plant; before entering the fight unequip Billy and set him to Idle, Team; once the battle starts move together to the very back of the arena, wait for boss to catch up, go around and at the next intersection move Billy forward with the right stick and then set him to Solo; continue the fight with Rebecca circling that back area)
Leech Queen 2nd Fight (after the previous fight; before entering this fight unequip Billy and set him to Idle, Team; once the battle starts use the right stick to move Billy off camera to the right, while moving Rebecca to the left; set Billy to Solo and continue the fight with Rebecca; in the lower left of the arena you will reach some stairs with Rebecca; draw the boss to you and take a step up the stairs; while standing on the stairs the boss can only damage you with his spitting acid and sometimes will decide to just stay still for a long time; sometimes the boss will just go for Billy and you can't change its mind till it gets one attack in on Billy)

Important thing is using the right stick to move Billy during a boss fight does not void this achievement. I'm not sure about Billy inflicting damage to the boss. Better to not risk it and have him on Idle, unequipped.

Thumbs up. Just for reference though for anyone attempting this, the achievement pops after the credits. For me it was when I got my rank. Don't freak out if it doesn't pop after the first Queen Leech boss. Also just to be safe I used Rebecca for the first half of the second Queen Leech battle (before you're forced to play as Billy and defend Rebecca).

Also for me I tried to get it during Wesker mode and it didn't seem to count.

Hm, you may have just messed up along the way because I unlocked it in Wesker Mode. You made sure to set Billy/Wesker into idle mode for the second Tyrant fight and first Queen Leech fight?

Yeah, Wesker had no weapons equipped and was set to idle while I killed them quickly with the infinite magnum as Becky. Although I don't think I killed the scorpion boss at the train with Rebecca in this playthough. Maybe all the kills have to be on the same playthrough?

Ahh, yeah they do. That's where the issue lies. Well at least playthroughs are quick with the infinite weapons.

I done 3/5 on my first playthrough on easy as I was playing fun and had rebecca connect power. I was sure I killed the other 4 mentioned with her though so weird it only says 3/5 on TA and 60% on XB1 tracker. I just done a new game+ whilst using no recovery items, no saves and mixing no herbs which all popped at the end. This never and still says 3/5. I killed all mentioned above with rebecca. The only thing he may have killed would have been queen in 1st form before defending rebecca. I should have still had 4/5 if that was the case. I used the magnum revolver all the way through, maybe that affects it? Gonna try wesker mode.

I used the magum revolver for my playthrough getting this achievement so that shouldn't be the case. You made sure to put Billy in idle mode and unequipped?

Yeah he wasn't shooting. I'm just doing my wesker mode playthrough and got to the queen fight in the incinerator room, the one you use the keycard. Had wesker idle and killed it myself and that added 20% to the XB1 tracker, so there I think there is an error in this solutions list. I have once again killed everything else with her so all it leaves is the queen again before the defend rebecca sequence. Il finish it tomorrow and let you know.

Yeah for the final Queen Leech battle I fought as Rebecca with Billy idle, even though it wasn't written in the guide. Not sure if it actually added to the percentage but I figured I'd do it just in case.

That actually would make a lot of sense. Seems that may be the case since that's how we both got it, unless someone proves otherwise.

Are you positive that the Marcus leech thing counts for this? From the tracker, it looks like there would be 5 bosses since it goes up by 20% each time. Also when you say "first battle", are you talking about on the Train or in the hallway in the Training Facility?

Ok I think I have this figured out. The achievement counter does not increase the first time you fight the tyrant. This is the fight you have to fight alone with Rebecca anyway. Here is the proper list and the order you should encounter them:

1. The giant scorpion on the train, so have Billy reconnect power and fall through the roof.
2. The Marcus leech thingy (first battle)
3. The infected bat in the church.
4. The prototype tyrant round 2.
5. Leech Queen Phase 1 (just after getting off the lift and before Rebecca starts activating switches)

That isn't a boss Reemiks, it's just a regular enemy

The Marcus leech thingy (first battle) is a special enemy, not a boss.

No, it's a boss. The one you have to fight in order to get the keys to activate the lift that takes you to the final boss fight.

Yeah so it just popped after credits. I used rebecca to kill it before you are forced to defend her as billy. What I think, it is the bosses that you can choose who to fight with.

Giant Scorpion
Infested Bat
Proto Tyrant 2nd encounter (where you go down a small lift and get motherboard after)
Queen Leech (Incinerator Room you need keycard to access)
Queen Leech Final Boss 1st phase (Before defending Rebecca)

I'm not 100% on this but I don't think the first proto tyrant counts as you are forced to use rebecca and you don't technically defeat him at this point. There is a possibility that either the last one on my list above doesn't actually count until the end credits, or maybe its another but I cannot be sure.

This achievement is a bit misleading and kinda tricky. First of all you need to control Rebecca mostly in order to make sure you claim each kill. You dont need to disarm Billy but doing so is not a bad idea. You need to kill the following creatures:

The scorpion at the start of the game.
The giant bat in the church.
The prototyrant, second encounter along with Billy. The first encounter doesn't count.
The leech queen. Both encounters.

Everytime you are doing it right a 20% of the achievement is completed. In the last fight, you will use Billy only at some time. I will not spoil anything but I think this 20% is before using him.

Take note that mini bosses like the zombified Edward and
the leech zombies aka Mimicry Marcus don't count. Same playthrough required.

Son cuatro los jefes que tienes que vencer para obtener el logro:
1. Stinger en la segunda planta del tren.
2. Proto Tyrant en la entrada del ascensor y en la planta eléctrica.
3 y 4. La Reina Sanguijuela en sus dos fases (para estos duelos te recomiendo no equipar a Billy con ningún arma).
Centurión es el único jefe que no cuenta ya que no es posible hacerle frente con Rebecca.
