3DS owners, it's a good job you like castles. Yesterday we had Castlevania: Lords of Shadow — Mirror of Fate confirmed and today Zen Studios — yes, the pinball guys — announced CastleStorm for "Nintendo digital platforms".
The tower defence/strategy hybrid was officially confirmed for the 3DS eShop but Zen has said it's in development for "literally every digital platform", so we're putting bets on a Wii U digital release later this year. Big bets.
As for the game itself, it's a side-on take on tower defence with a dash of physics-based play in there too. The trailer below explains more.
Zen Studios will be at E3 next week so we should see more.
