Suddenly, numerous monsters appear and Gensokyo is once again in danger of destruction. Touhou Battle Raiders is a strategy RPG developed by four doujin circles; Hachimitsu Kumasan, AQUA STYLE, Strawberry Bose and Kanagawa Denshi Gijutsu Kenkyuujo. Through the campaign, the player retains control of four characters, across a battlefield against hordes of enemy forces in real-time with boss battles at the end of each round. In the campaign the player must complete the main objective to proceed to the next chapter, but there are also optional routes which can be completed alongside the main quests with rare items as reward. In between battles, players can access their characters to equip them with purchased goods or items gained from previous adventures.
