Resident Evil Zero HD: Unlocking the door to the observatory

At the end of your visit in the facility, you will have to solve a puzzle in the Observatory. You will need three stone tablets for this. One of them is Unity Tablet that you've found in the basement (M3,8) (description in the Basement chapter). You can put it away for now (for example place it near the typewriter in the hall) and go look for other tablets.

You can use the key from the basement to open the door on level 2F of the facility.

Choose the eastern door on the higher level of the main hall. They lead to a narrow corridor with stairs (M2,11). Go to the eastern room when you've defeated mutant insects and found the grenade launcher (M2,12). You can use the Facility Key that you've obtained in the facility (the test area with hunters) and open the door in this room. Before you go any further, make sure that Billy is using the grenade launcher and that it is equipped in Napalm Grenades (if you don't have this kind of ammo, look for it in the rooms that you've already cleared).

The handle can be found in the room with the second leech zombie.

In the next corridor (M2,27) there is a leech zombie behind the corner. The corridor is very narrow so you have to defeat the monster and it is good to use Napalm Grenades. After you deal with the zombie, don't go further, but instead use the door on the left, near the starting place (M2,28). They lead to Broadcast Room. After going in, head right and defeat another leech zombie. You can now explore the room to find Vise Handle.

Billy has to play the piano.

Return to the corridor and continue walking. Open another door leading to a bar (M2,29). Besides some supplies, there is also a piano here. Try to interact with it as Rebecca and you will earn an achievement/trophy. Switch to Billy and play the right melody on the piano. You will unlock a secret passage. Order the partner not to follow you and switch to Rebecca. Enter the secret room, approach the device on the wall and pull out the Battery. Doing this will lead to closing the exit. No need to panic, you just need to switch to Billy and play the piano again.

Exit the bar and approach the next door. When you are in a narrow corridor (M2,30), turn right and explore the north-eastern room (M2,31). Get rid of the zombies and locate the vise shown in the screen above. Select the character who has the Vise Handle and use it on the vise. You will unlock Obedience Tablet, which you should take. Exit the room and reach the western room (M2,32), which is the last one that you hadn't yet explored. There is a lot of medications in this room

The door leading out of the building.

Now you have to return to the main hall (M2,3), but be careful, because after leaving the last room, you may be attacked by a leech zombie. Quickly use the grenade launcher to eliminate the monster. When you are back in the main hall, consider saving the game and approach the door between two standing armors. Using this door will take you out of the building (M2,33). Head right and you will find a broken elevator. Select the character who has the Batter, approach the slot on the wall and place the object there.

You can now interact with the elevator mechanism to use it. You will find a large crate inside the elevator. Approach it, climb on top of it and stand on the other side (like in the screen above). Turn 180 degrees around and push the crate out of the elevator.

Now start pushing the crate left and then towards the bottom of the screen. You should move the crate to the column shown in the screen above. Climb on top of the crate and collect Discipline Tablet from the column.

The door is in the room where you fought the mutant centipede.

Now we can proceed to the puzzle in the observatory. If you want, you can go to the observatory several times and carry the tablets one by one or try to fit them all in the inventory at once. For the start, go inside the building again (M2,3). Go to the higher level of the main hall and use the eastern door leading to the narrow corridor (M2,11). Go up the stairs to level 3F where you fought Centurion (M2,10). You can meet some mutant insects here (use the rifle or grenade launcher to defeat them or escape them). No matter what you choose to do, take the northern door (between the two standing armors).

The place to which you have to carry the three tablets.

Using the door will take you to the observatory (M2,34). Go across the balcony and locate the ladder leading to a higher level (M2,35). Find a panel with three slots. You need to open the inventory and take out the tablets that will be automatically placed in the right slots. Placing all three tablets in the right place will trigger a cut-scene. Go back up and use the door to go to the next location - Laboratory.
