Viking Invasion made it out for DSiWare a couple of years ago. BiP media has today revealed a sequel for the eShop.
Officially titled Viking Invasion 2: Olaf’s Return, the game will feature new Viking units, new towers, and more. It seem as though there will be some sort of divine intervention/periodic superpowers as well. Players will be able to experience the the game in 3D.
Viking Invasion 2 is currently without a release date. You can find some concept art of the project in the gallery above.
