Koei Tecmo uploaded a live demo video, featured above, which shows off Bladestorm: Nightmare‘s Edit Mode. This mode allows players to create custom mercenaries. There’s more than thirty minutes of customization; although it’s warranted, since the options seem to be incredibly particular, you’ll probably just want to jump around to get a general idea.

The description attached to the demonstration is quite a good summary of the game:

Bladestorm: Nightmare is a strategy game where the player takes the role of a mercenary and chooses to fight either for England or for France in missions inspired by real events and battles of the era dubbed ‘the Hundred Years War’ (1337-1453). […]

Omega Force has developed this title in a way that allows the player to assume command of different kinds of army units, while it also offers them the opportunity to develop their own unique character, increase their fame, gold, and army and complete various missions irrespective of sides and loyalty. […]

Bladestorm will also include a stand-alone mode called Nightmare, which features an original, fictional scenario. […]

This fun new twist diversifies the classic strategy elements of the game, and effectively splits Bladestorm: Nightmare into two parts: Bladestorm, the historically accurate account of the 100 Years’ War, and Nightmare, a fictional fantasy scenario that unfolds in the same world.

Bladestorm: Nightmare is releasing on March 17 in North America and March 20 in Europe, for the Xbox One, Playstation 4, and Playstation 3.
