So, I finally managed to get the other prisoner to follow me, but all he does is needlessly offer to check out the secret passage. I still can’t get past the sentry gun, although I was sure that ‘Bathroom’ was key to achieving that.
there is a way to make the monster grow, and the bigger monster is able to destroy the sentry. (But this is the complicated solution. The simpler one is that there is a specific item that can stop the sentry by drawing its fire...)
