With less than a month to go before Sega's Viking: Battle for Asgard goes live, the game publisher announced a small added bonus to sweeten the deal for customers who want to pre-order this Norse-themed action title for the Xbox 360 and PlayStation 3.

For those of you who aren't familiar with the game, Viking puts you in the role of Skarin, a Viking warrior who tries to save the realms of Midgard and Asgard from the goddess Hel at the behest of the Norse gods.

Taking a look at the screenshots and trailers we've previously seen from the game, Viking definitely looks like it's going to be another engaging hack and slash action title that gamers can really sink their teeth into.

Anyone who wants to pre-order Viking: Battle for Asgard from GameStop will get the exclusive chance on scoring a free concept art book along with a copy of the game. At US$ 59.99, the offer is definitely a steal for anyone who wants to get some free stuff with their game.
