Bladestorm: Nightmare is a tactical action game developed by Omega Force and published by Koei Tecmo. Released in 2015 for PS4 among other platforms, it serves as a revamp of the original 'Bladestorm: The Hundred Years' War' with added fantasy elements. Players lead squads in battles set in a fantastical depiction of the historical Hundred Years' War between England and France. They can switch between troops and control different units, using strategy to manipulate the battlefield. The game's 'Nightmare' mode introduces fictional creatures into the mix, ramping up the fantastic and historical blend.
