Level C 742

生存难度：生存難度：

等级等級 4

• 精神干扰
• 有限氧气
• 难以逃脱

这里所摄下的一幅照片

Level C 742是后室C层群的第742层。
描述
本层大概是一个4m*1m的长方形空间，高6m，且本层唯一的光源就是头顶的长条探照灯（会发出类似于level 0荧光灯的嗡嗡声）。本层的墙壁由一种褐色的大理石质感的墙壁围成。且本层地板有沙质感。本层空气中弥漫有大量的地下室潮湿气味。
特性
经检验本层的氧气只够个人呼吸15分钟左右，且四周墙壁始终发出未知奇怪的响声（无法确认声音是否来自实体或其本身就是实体）。这种声音会对流浪者造成精神干扰，会使流浪者感到越来越烦躁直至绝望。
基地、前哨和社区
由于本层的空间因素以及特性，本层无法建立任何基地等
入口和出口
入口

• 找到任何一个小于4㎡的空间并待上大约5分钟你就会来到这里

出口

• 打碎头顶的探照灯周围会迅速黑暗（但由于高度的问题逃离变得异常艰难），随后在远处会出现微弱的亮光，跟随亮光你会来到Level 9的一处路灯下
