BiP media has announced the North American release of Viking Invasion, a strategy game that pits a band of numb-skulled Vikings against defenders with a dodgy sense of humour. The adventures take the fearsome warriors of the North into a comical, off-beat world where they find themselves developing strange cravings for tulips and cream cakes. The Vikings have a range of sea-going attack units, from their longships to the Norse god Odin and a whole range of fantastical creatures. And the defenders can build different types of towers and strongholds to halt the enemy's advances. Viking Invasion is now available via DSiWare.
