this layout is provided by the game and probably is the most bland, lame and unoriginal of the layouts. if you see someone playing with this they are either new or have just started this campaign.
If you use this as your actual layout you might need to call 911.

This is a very popular and good layout because it allows for you to quickly open/close doors as well as disable turrets for you teammates because it is positioned very close to the cameras. honestly a very useful and fresh looking type,
aslo comes with an optional replacement for closet by putting it closer to the terminal instead of next to the door.

this one just makes a lil barrier between the person on the terminal and rest of the crew.
potentially helps against mimics but not sure also optionally puts closet closer to the terminal and cameras.

basically if you have teleporter protects in case you accidentaly teleport a mimic inside, if you want to enter just press b on the bed and then e to put them back in the otiginal place.also seperates captaim/terminal user from the rest of the crew and creates false sense of security

place the terminal closer to door to insure maximum time when opening/closing doors and disabling turrets, also very good because there's a lot of space that you won't do anything with, gives minimum on a vibe check score.
please don't use this.
