River Castle is a first-person shooter. Waking up after a plane crash, before you lies an old castle by the river. Having reached the castle, you learned that experiments on demons are taking place there and need to wait for help. How long can you stay alive, escaping from special forces and demons that are armed to the teeth? Use weapons taken from fallen enemies or in secret places. Are you ready to fight for survival? Good luck then!
