Resident Evil Zero HD: Exploring the testing area

Return to the room with animal statues and go to the North-Western door that you have been ignoring so far (the one next to the room where you have recently saved Rebecca) (M3,10). Thanks to taking the door, you reach level B3 (M3,11). Climb down the stairs and expect giant spiders around the corner. You can kill them all out, just like you did previously, or dash to the Southern door.

You will get into a small room with waterfall (M3,12). Stay vigilant here, because there are insects on the left. Sneak up on them and use the shotgun, or the grenade launcher, to get rid of them. After you have cleared the area, find the Locker Key. You can now return to the corridor with spiders and go to the Northern door.

After you walk into a new area (M3,13), climb up the stairs Around, there is lots of ammo and, of course, it is a good idea to replenish your supply. Apart from that, you can use the Locker Key that you have just found, to open the locker. Collect the Duralumin Case. Examine the case in your inventory and you find the code: 385. Turn the case in the way that allows you to enter the code (the above screenshot). You can collect the Handgun Parts. The mentioned parts can be used for upgrading Billy's or Rebecca's gun. Open the inventory of the selected character and combine it with handgun. As a reward, you receive a more powerful Custom Handgun.

Make sure that you are playing as Billy and that he has the Grenade Launcher in him, because soon it will be VERY helpful. Apart from that, have Rebecca stop following Billy. Climb down to the lower level and explore the side corridor that you have ignored earlier. Switch to Rebecca and interact with the control panel at the upper floor. Press the left button - L.

Switch to Billy and take the newly-unlocked door below. Examine thoroughly the available part of the room, thanks to which you find Acid Grenades on the floor. Switch the launcher to this type of ammo. Remain in the spot, where you have found the grenades, switch to Rebecca and press the central button.

Again, switch to Billy. Go to the bottom of the screen and follow the narrow corridors to the locked grate. Remain here, switch to Rebecca and press the central button again.

Switch to Billy, make sure that you have equipped the grenade launcher and approach the red button shown in the above screenshot. Press it.

Pressing the button results in a fight and there appears a new variety of monsters in the room - (hunters). Use the launcher loaded with acid grenades. Try to be accurate and not stand around for too long, while targeting the hunters, because they are very agile and they deal quite a lot of damage. Continue up until you kill all of them.

After the fight, heal Billy and turn to the locker shown in the above screenshot, near the red button. Here, you find Facility Key. You can now command Rebecca to follow Billy and leave the basement the same path you came. Your destination is now the main hall of the training facility (level 1F) (M2,3) and it is a good idea to use the typewriter there to save your progress.
Note - If you have not collected the Unity Tablet from the room with the animal statues, it is a good idea to do this now. Thanks to this, you will not have to return to the basement later.
