Loki is a big smelting pot of all the interesting bits of mythology through the ages bubbling away on Cyanide's (the developers) little stove. Allowing you to play as various heroes from all through the ages, from Norse warrior to aztec shaman, you get to battle your way through a large variety of enemies from trolls to cyclops!

A second demo of the game has been released, where you start out as a level 12 Egyptian Sorcerer, which is a nice change from the normal "start at level 1" demos seem to like to hit people with. Check it's 1.22gb out at FilePlanet
