Dweller 1.22.3 continues to build upon the recently introduced Sewers side branch. There's now a second floor to explore, a really bad-ass Ratking end boss (BTW check out indie devs Rat King Ent.!) and a nice little reward for slaying him.
The new version also introduces properly locked doors that require either a) a key b) a set of lock picks or c) a heavy weapon.
The frequency of locked doors and the availability of master keys probably need to be adjusted. I am also a little concerned that the Sewers are too difficult and need to be introduced one dungeon level further down (or swapped completely with the Labyrinth). Please provide your feedback here or join the Dweller community at the official forum.
