Level 45 is a collection of 45 basements. These basements have dry, concrete walls, which is a direct contrast to the floor, which can become so wet that it starts to form puddles. It is also extremely humid and can reach 32°C (around 90°F).
These Basements have varying size, from being the size of an average bathroom, to being the size of a small town. These basements also have varying layout, from having nothing in them, to practically being a maze with multiple floors. Although this level is small, it's layout can change at any time, although it will never trap wanderers in. Physical objects (besides things that wanderers bring in) are impossible to move, so if its blocking your path, you'll need to find another way around. As there are no lights on (when you first enter this level), the only consistent light sources are small windows. These windows are impossible to both break or open, and if you touch them, you will be sent to Level !. The only other confirmed way of leaving is waiting 6 hours for the lights to turn on, then leaving through any door, which takes you to Level 11. If you choose to do this, over time you will suffer decreased sanity, paranoia, memory loss, and possibly permanent brain damage. There can only be one person in here at a time.
Entities
Second photo taken by (Redacted) as they were leaving.
There is only one type of entity here, The Basement Wanderer, which are tall, black, humanoid creatures exclusive to this level and are very hostile. There are always 45 of them here at any time. They have poor eyesight, however they can run at 12 MPH, are very flexible and have amazing hearing. If you see one, you should run away, hide and be quiet.
Colonies and Outposts
No colonies have been confirmed to exist, but it is rumored that E.M.F.A. has a small outpost here,
