You sure you are not playing on hard mode? There really are not that many lickers in the game. 3-4 shots with the shotgun deals with a licker on standard mode.So I’ve just seen a certain someone after going in the sewers, and now back in the police station. In every other corridor I’m going in, there’s a licker. No exaggeration. Either that or the same one is moving when I move between rooms
Also if struggling you can use the environment to your advantage in this game. For example lickers cannot go from one room to another. Just go in and out of a door, never get hit, take time and place shots
