'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). Revisiting one of the lengthiest and most politically unstable periods in European history, 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.
