Arx – End Of Sun is a fan made modification / total conversion that is based on the first person dungeon RPG : Arx Fatalis, developed by Arkane Studios. This is a fan made prequel to the original story of Arx Fatalis.
Here you see the player about to be attacked by a pair of cave rats. This is in a section of the mineshaft map that leads between two different cave systems. Although quite hard to make out in this shot – we now have new player arms too, so no more doom-guy hands.
