Fury Files has been updated . . .
I just typed in my code at www.furyfiles.com for Captain America (reviewed here) and it worked. It looks like all of the Wave 2 figures have been unlocked, but I haven’t taken the time to test the site yet.
The alternate-universe Cap info under the secret file is leading to something.
Update: Both Hulk (reviewed here) and Green Goblin (reviewed here) are also active, so it looks like all of Wave 2 is definitely online.
