We're not much for pre-ordering stuff (honestly, if you're a store, shouldn't you have things to buy?) but when we saw that the Collector's Edition of Batman: Arkham Asylum included a batarang, it was, frankly, out of our hands. But the pot just got even sweeter with GameStop's announcement that those who pre-order the game will get an exclusive Challenge Map.
The map, "Dem Bones," will see Batman face off against an army of Scarecrow's minions. But frankly, the above image contains all the information you need to make a purchasing decision: Batman. Versus. Skeletons.
