Wargroove comes out 1st February.
The announcement was made as part of today's indie-focused Nintendo Direct. Wargroove launches on 1st February on Nintendo Switch, PC and Xbox One.
Wargroove is a turn-based strategy game that's like a medieval Advance Wars, and very promising it looks, too. It's made by Chucklefish, the developer of Starbound and the publisher of Stardew Valley.
