If you found yourself spending hours playing Angry Birds, then here’s something even better: a new online game called Thor: Hammer of The Gods.

In this free web game, which is a tie-in to Marvel’s upcoming Thor movie, you fight in Asgard as Thor against the Frost Giants. When you defeat enough enemies — by throwing the mighty Mjolnir, Thor’s hammer! — in a certain amount of rounds, it unlocks trophies, which contain footage from the film and character bios. You can also choose to sign into the game through your Facebook account so you can compete against others.

I’m not going to lie, this game is addictive. Once you wield the power of Mjolnir, you just can’t stop! Check out my badass score in the screenshot above — not bad for my first try! (I probably would have done better had I maybe read the brief instructions on how throw the hammer, but I don’t have the patience for that.)

Marvel has released a new interactive widget for Thor called Thor: Interactive Guide to the Universe of Thor, which contains new images and footage from the upcoming film.

Browse through the interactive guide here below to get a look at new and existing footage from the film, as well as images, artwork, character bios, and location descriptions from the universe of Thor.

As you browse through the sections, you’ll unlock new content. Once you’ve unlocked 100 percent of the content, there’s a nifty “Easter egg” for you to download.

Thor, which stars Chris Hemsworth as Thor, along with Natalie Portman, Anthony Hopkins, Kat Dennings, Stellan Skarsgård, Ray Stevenson, Clark Gregg, and Rene Russo, is directed by Kenneth Branagh and will hit theaters on May 6, 2011.
