Here's an interesting bit of cross-promotion, assuming it's for real. I think we can all agree that Mass Effect 3 has transformed into something much larger than a video game franchise. There are books. Comics. An upcoming movie. And, most relevant to today's discussion, action figures. Product listings for the set of eight upcoming ME3 action figures at BigBadToyStore.com (via MCV) all contain an added note about bundled DLC.
"Each figure includes an in-pack card giving you access to downloadable in-game bonus content. Each figure contains different in-game content, exclusive to North American released product. Collect all 8 for the full experience!"
There's no further indication of how the DLC will work -- probably through your personal EA account, since platform-specific codes would require that three versions of each action figure be offered -- or what the content is. It could be anything from weapons/armor/tools to full-blown quest content. I've reached out to EA and will hopefully have some additional details to share soon.
