Also, maybe the mutant was helpless and prone at the same time after you hit him? He WAS pretty messed up...))
((This, defenseless enemies are even easier to hit then flat footed ones.))
That also didn't mean he would make an effort to stay silent.
((He might not have made an effort but my RNG seems to have taken a liking to 1s and 20s all of a sudden. Guess which one the mutants rolled for detection?))
Troy slips further along the tracks stealthily. Ethan nonchalantly swaggers behind him but is stopped short by Rain grabbing him by the scruff of his neck. She stares at him quizzically for a second. "Keep it down" she hisses in a low whisper.
Troy slips ahead while Rain detains Ethan and comes right up to the edge of the concrete platform without any shouts of alarm. He hears the mutants jabbering sporadically but they don't seem to be moving or giving shouts of intimidation. Troy glances over the edge of the barrier and sees them; three mutants huddled around a fire, jabbering at each other. They seem to be in the middle of some sort of scuffle, pushing each other around and completely oblivious to the outside world.

Right is the direction the party came from. The tunnel curves but that's kind of hard to show on an ASCII map. Left the tunnel is more rubble strewn and possibly collapsed but it's not clear in the darkness. Top of the map has a small entrance/egress that you can't make out well. Empty space near rubble is rubble strewn but walkable.
Mutants are currently oblivious.
