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).

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.
