i played it on normal quite a bit until the level came with the molotov cocktail guys.

Always just being able to hit shotgunners and such with crowbar only was a paina nd quite hard but this is just impossible.
HOwever i also never found a gun anywhere.
dudes rarel dropped gun ammo but couldnt use them without a gun.
so crowbar it is where I just cant beat a molotov guy, a shotgunner and a melee enemy all at once with my crowbar alone :-(
