Saving Rebecca | Training Facility Basement Walkthrough Resident Evil Zero HD Guide
Last update: 02 February 2017
From now on, you will be playing as Billy and in spite of what you might be thinking, you do not need to race against time here to get to Rebecca as quickly as possible. Prepare the shotgun, just in case, and return to the small room with the typewriter (M3,2). Quite unexpectedly, there appears a mutated monkey there. You can dash by the monkey (you do not need to visit this room again, later into the game), or kill it. In the case of the latter, fire the shotgun as quickly as possible, because the monkey is very agile. After you get into the corridor, where you have earlier killed spiders, consider exploring the Monitor Room (M3,5) that has just been unlocked. There are zombies there, but you also find there, e.g. ammo.
You now need to go towards the opposite part of the basement that you have already been exploring, and the access to which has been obstructed by hot steam (it disappeared after you have solved the puzzle with setting the right voltage) (M2,15). Return to the main hall of the Training Facility (level 1F) (M2,3) and consider saving the game, before you proceed on. Take the Eastern door to the dining room (M2,13) and expect to encounter some more zombies (you can either kill them or escape them easily).
Take the Northern door that you can see in the background. You walk into the narrow corridor that you have already been to (M2,15). Take the left (Western) path thanks to which you get to the newly-unlocked passage that has been shown in the above screenshot. Proceed along the path, up until you reach the door into a new area in the basement (level B2) (M3,6).
In the next room, there are at least two monkeys and it would be a good thing to deal with them right now, because you will soon get here a new puzzle to solve. It is best to remain in the starting point and fire the shotgun at the charging animals. After the fight, ignore the animal statues, for the time being, and head West. At the end of the corridor, there is a door, but do not open it. Instead, go right and take the door to the room with Rebecca in (M3,7). Here, you will watch a cutscene of rescuing her.
