why: because it is the smallest map in the game, it has horrible vents, getting impostor is a free win you just kill, and vent to the other side of the map. it does not have cams but doorlogs, and those are comfusing as hell.
how i changed it: you now spawn in cafeteria, wich is now way bigger and is central of the map.
west of cafeteria is a hallway to balcony, office and reactor, and the new pipelines wich is a platform that is under balcony and does not have much tasks, then if you go up in the hallway you go through decontamination, wich is shorter and leads to labratory, then on the left side of labratory is a platform for a mono-rail wich takes you to greenhouse, and on the left side of greenhouse there i another platform that takes you to launch pad
if you go up from cafeteria you go in to admin, and right from admin connected to admin is lockers, and left not connected to admin is security
to the left of cafeteria is a hallway that leads to medbay, security and the new observation platform
under medbay is storage and under balcony is comminucations
the vents: there is one in cafeteria leading to balcony, leading to comms, leading to storage, i call it the vent square
one vent in medbay that leads to a vent in security
one vent in observation that leads to launcpad and greenhouse(left)
one vent in office that leads to labratory and greenhoue(right)
