IGN show you what $100 and a bat obsession gets you.

A Collector’s Edition has been released by GameStop. The package features a 14 inch Batarang in the style of the game, a 50 page character journal, a bonus DVD or Blu-Ray disc (depending on whether or not it is for Xbox 360 or PlayStation 3) including interviews with voice actors, an exclusive Crime Alley Challenge Map, and a Batarang Box Set.

Additionally, an exclusive preorder challenge map from Gamestop was announced called ‘Dem Bones.’ It features the Scarecrow and places Batman under the influence of Scarecrow’s ‘fear toxin’ causing him to hallucinate and all the enemies to be seen as skeletons.

Batman: Arkham Asylum is an action-adventure stealth video game for Microsoft Windows, PlayStation 3, and Xbox 360, and is based on DC Comics’ Batman.

It was developed by Rocksteady Studios and published by Eidos Interactive in conjunction with Warner Bros. Interactive Entertainment and DC Comics and was released on August 25, 2009 in North America and August 28, 2009 in Europe.

It is based on the long-running comic book mythos, as opposed to most other Batman games which are adaptations of the character in other media besides the source material.

Arkham has been well received so far, and holds a 91% at GameRankings based on 12 reviews. Metacritic currently holds the game at 91% (based on 13 reviews).

The first review of the game was published by GamesMaster. The magazine awarded Arkham Asylum a 96%. Blogger RamRaider criticized the review and accused Eidos Interactive of review fixing. However, these claims remain unsubstantiated.
