BioWare announced plans to release a limited supply of Mass Effect 2 Collectors’ Editions when the game launches this upcoming January.

Included in the upgrade: the obligatory tin case, a 48-page hardcover art book, the first issue of the upcoming comic, a behind-the-scenes DVD, and a special suite of in-game armor and weapons. According to BioWare co-founder Ray Muzyka, “We’re all really excited to roll out this Collectors’ Edition featuring so many unique items, including special Collectors’ Edition armor and weapons and content that will surprise Mass Effect fans.”

What’s that about content?

The Collectors’ Edition will be priced at $69.99. Tin cases, DVDs, and two-inch tall “art books” are well-worn territory for collectors’ editions, but it’s interesting to see BioWare rolling out extra content like this for their games. Bonus items (like Dragon Age: Origins’ wolf charm and magic ring trinkets) don’t offer much beyond making the game almost imperceptibly easier, but “surprising” game content might really push fans toward buying an upgrade. Is it a clever way to get people to buy up, or is it just a sneaky marketing gimmick? Discuss on the boards.
