Sif has been kidnapped by the Enchantress! Trolls are loose in Asgard and you need to stop them in their evil tracks before they wreck your beautiful floating kingdom. The game plays a lot like Mega Man.. you'll see if you land on some spikes, which is funny because if that really happened to Thor they would probably flatten under his feet. Anyway use the X key to throw your hammer and the Z key to smash troll faces with it up close and personal. Jump with the up key and move around with the arrows keys. Also call on a lightning shower when you have 3 lightning items stored up and it will clear the screen of bad guys.
