In Resident Evil 7, you can explore the mansion in any order. You don't need to solve all of its puzzles or find all five of its collectibles in a single playthrough. If you get stuck on a certain puzzle or section, try exploring another area!
You can walk around the attic, but there's nothing to do there. You can go through the door into the attic at any time and explore it if you want to see what it looks like. However, you cannot get out of the attic; even if you go through all four doors, one will always be locked.
The attic is not a secret room. It's just where the main house's attic would be if it were real. You can go up there at any time, but you can't get out of it, and you don't need to get out of it.
You can go through the door into the attic at any time, but you'll find nothing there. The only thing there is to do is explore and see what's up there.
You do not have to find all five of the collectibles in one playthrough unless you're playing on New Game+.
As with most games, there are multiple ways to approach Resident Evil 7. You can find each collectible in a single playthrough, or you can go back through the game and gather them all at once. You also have the option of finding them in separate playthroughs (which may be easier if some of them are difficult).
However, if you want to make things really easy on yourself and get everything done at once without having to replay too much content over again, then we recommend starting up a New Game+. This unlocks after beating Resident Evil 7 for the first time; it allows players who've beaten it before access to some extra difficulty settings that make enemies tougher while also giving players more ammo and health items throughout their journey through this survival horror masterpiece!
Resident Evil 7 does not require you to complete every level in order to advance through it. If you're playing on normal difficulty, you can go through the door into the attic at any time and find nothing there. You won't need anything from this area until later on in your playthrough, so don't worry about it if you want to move forward now and come back later when it's more convenient for your progress through the game.
The only exception here is if you're playing on New Game+, which means that all of your items will carry over from previous playthroughs (and any collectibles found during those playthroughs). If this is the case for your game and some of those collectibles are still missing after completing all four main chapters, then feel free to explore other parts of the house while waiting until they show up again!
You can't get out of the attic in Resident Evil 7, just like you literally can't get out of your own skin. The attic is a symbol for your mind and the place where you can't escape from yourself. You have to face what is inside of it before you can move on.
You'll want to make sure you've completed all four of the optional side quests that are available at this point. These are The Madhouse, The Cellar, The Nightmare and Sewer.
Once you've done that, there will be a cutscene that shows Lucas Baker starting up a chainsaw. He'll be in a different room and angry as hell, so it's time to get out of there!
After running away from him, go back down into the basement and use your camera to zoom in on his face while he's sleeping. This will make him wake up and come after you again.
After doing so, head back upstairs and find a note on the desk that has been moved since last time you were in this room. Read it and it will tell you where Lucas went, as well as what happened to Ethan.
Ethan will have to go through a secret passage behind the mirror he had previously looked into before reaching his destination: an underground facility containing more Umbrella soldiers and plenty of other surprises!
Once you've gone through the mirror, you'll find yourself in a room that looks very similar to the one where you initially started. The only difference is that now there's no way out of it except for going through another mirror on the opposite side of this room.
Once you've gone through this second mirror and entered into another room, turn around and look at where Ethan was standing when he first entered this area. You'll see something strange on top of one of those crates stacked up against each other: an item called "Note." Pick it up with X/Square (or A/X on PS4) and read what's written inside: "The attic key is hidden in one of three locations: behind either left or right mirror or inside desk drawer."
If you don't know how to complete this puzzle yet, come back later after completing all the optional sidequests!
The note can be found in the attic of the house on the east end of Cottonsmouth. It gives you instructions on how to find a secret passage behind a mirror in your room.
Resident Evil 7 is a game that lets you explore and find your own way through it, which means that you can go through this particular level at any time. You don't have to get out of the attic; all we're saying is that if you do want to explore there, then go ahead! It won't affect how much fun it is playing through the rest of the game or even how scary it feels when something pops up behind your back unexpectedly.
