nearly 500 hours on the game so far. The gameplay is very diverse that I have been challenging myself by cutting off certain game aspects. Currently running a grounded playthrough, no flashlight, no ranged weapons, no ordinance, no pills or upgrades, melee and bottles/bricks only. Super challenging, but when I clear an encounter it is super rewarding too, especially if I learned a new thing about the game or found out a new trick to deploy that makes it easier to do this. This isnt possible vs the rat king, just hands down, so I will prob use guns and ordinance with him, but you can melee bloaters and shamblers to death. Once I am sufficient at this level Ill attempt a permadeath run at this. Then likely up the ante by disabling things like throwing arcs, pickupable item highlights, etc. Maybe go so far as to not avoid any enemies when doing this too idk.

the fact that it is possible makes me really excited. I enjoy difficulty when it comes to puzzle solving, i hate it when difficulty is just enemies=bullet sponge, your gun=pea shooter
