 entity 463A's are mutant aggressive entities that live here. These are all over the level and they are what used to be normal entities or people that got nocliped here and stayed in their radiation for too long. And their radiation turned their bodies into these hideous looking things. Now they all do look different, but all of them are strictly misformed with extra legs and arms and it just all looks gross. These entities will chase you onsite so you need to walk carefully in order to not be seen because they don't stop chasing you if you're seen.
