More Mass Effect 3 DLC Bundled With Artbook

It appears that ordering $150 worth of action figures won't get you access to all of the DLC BioWare is planning to release for Mass Effect 3, as Dark Horse has announced that exclusive "character boosters" and "the deadly Collector Assault Rifle" will be handed out to anyone who pre-orders The Art of the Mass Effect Universe from Barnes & Noble before February 20th. Amazon sells the book, too, but it looks like this is a B&N-only promotion:
"This product contains a code that can be redeemed for bonus content for Mass Effect 3 multi-player including character boosters and the deadly Collector Assault Rifle to give you a leg up on the Reaper invasion.

Visit social.bioware.com/redeem for instructions on how to unlock your new upgrades.)

(The Collector Assault Rifle uses the same principles as a human assault rifle, but its organic components clearly set it apart. Its power source appears to be an internal organ with biotic capacitance; its ammunition resembles pellets of metallic enamel that strip shields off enemies with deadly efficiency.)
