Rain Games announced a retail release of their game Teslagrad. The game is the second Wii U eShop title to get a retail release (first was DuckTales: Remastered) which has been confirmed to be available in Europe and the Americas in early 2015. The PS3/PS4/PC versions, instead, will be released on December 3rd.
At the time of writing this, no release date was given, however, we think it should be around $19.99 considering its digital value.
