Extending the idea of collector’s editions to ludicrously expensive levels, publishers Eidos and Warner Bros. have officially announced the CE for Batman: Arkham Asylum, which is due out on PC, PS3 and Xbox 360 this summer.

Priced at $100, a $40 premium over most other collector’s editions, the package will come with the game bundled with a 14″ Batarang (with stand) that matches the in-game design; a full, embossed leather dust jacketed Arkham doctor’s journal; 2 sleeve Digipak containing the game disc and a behind-the-scenes DVD; and a code for the exclusive downloadable challenge map “Crime Alley”. Oh, and a full-color manual.

As a silver lining of sorts, the regular PC version of the game will cost $49.99, $10 cheaper than the console versions.
