Sideshow Collectibles, the makers of the smexy limited edition Shepard figure, is holding a heck of giveaway this month. Until February 28th, you can enter to win a Shepard Premium Format figure, with the optional helmetted head, along with other goodies.
You can enter the contest by going here. The winner gets a helmetted Shepard figure (with Vanderloo's head option) as well as copies of Mass Effect Trilogy on PS3 and Mass Effect: Paragon Lost. This is a very limited run that's already sold out, so this may be your only option to get your paws on this version. Sideshow is still taking pre-orders for the VanderShep figure, however.
Another important point to note is that, should you win the giveaway, you'll have to cover shipping costs.
