The Unbirth Challenge

[Black Rabbit]

hmm, I think that can be solved by having enemies extremely hard to kill. Like 5000 hp against the knife damage of 10.
I don't yet know what the knife is for tho. Isn't there a pistol too?

or you could just make the weapons breakable and remove all of the firearms except maybe a revolver...with limited ammo of course...extremely limited and if the battle system with melee is like penumbra it will be very hard so it will be a challenge
