Grand Kingdom is a highly designed turn-based strategy game where you can choose and command a team of mercenaries to fight for the future of the fantasy world Resonail. Many kingdoms with quirky names, such as Landerth, Fiel, Valkyr, and Magion, are trying to gain power. Only you can succeed and become the so-called Grand Kingdom.

Developed by MonoChro and curated by the strategic JRPG experts NIS America, the game has a classic feel where you battle enemies on a 2D battlefield, consisting of three lanes, taking turns to spend action points, in a manner reminiscent of Valkyria Chronicles.

When not in battle, missions unfold in a game world reminiscent of a board game, with pieces representing your team and enemies, as well as a target flag for which you must plan a route filled with battles. With a limited number of available turns, there are many traps and random disasters to deal with, requiring at least some tactical strategy.
