level 1

Level 1.1 is a straight, narrow corridor in Level 1 that stretches on for an undetermined distance. The walls are made of cinder blocks painted white, and the floor is blue tile. Much of the level follows this blue and white colour scheme. Occasionally, exposed piping and ventilation ducts appear through cracks and holes in the walls and ceiling. Much like Level 1, Level 1.1 is abundant in resources because of the many crates filled with supplies scattered throughout the level. However, these crates become less frequent the further one ventures into the level, making it difficult for explorers to travel long distances. Explorers are not separated upon entry in Level 1.1, making it possible to travel in groups. This has led many explorers to embark on expeditions through the level. Many attempts to reach the end of Level 1.1 have been made, but none have succeeded. This is not due to inaccessibility or the distance to travel, but the dangerous variance in overall safety and entity count. 

Level 1.5 is a mysterious level that appears to be ''in-between'' the others. Thought to be a Sub-Layer of some sort, the level is not difficult to access but has been proven difficult to exit. Only one individual has described the level in depth, u/Chaosraider98 from Reddit who mistakenly entered the level during an exploration and has been unable to return to normal levels since.
