In the interest of keeping everyone current on free stuff, I thought it would be nice to have a thread with the active promo codes for the game in case you don't know where to find them. Below are the active promo codes, and I will keep this list updated as new codes are added and old codes expire.

To redeem a code, login to your account at marvelheroes.com, click on the profile link once you've logged in, select the REDEEM KEY option in the panel on the left, and enter the code. Once the code has been accepted, the indicated item(s) will show up in your character inventory in game right away, though if you are playing, you may need to log out and log back in for that to happen.
Please let me know if any of the codes are not working and I will update the list.
