Crimson Tears is a futuristic 3D action game set in Tokyo, year 2049. Players take on the role of one of three inhuman "biological war weapons" that must battle hordes of enemies and manoeuvre through maze like environments as they investigate the cause of a mysterious disaster that has left the city incapacitated.
Crimson Tears features distinctive cel-shaded 3D characters and fast-paced fighting action intermixed with stylish CG movie sequences that unfold the enigmatic sci-fi story. The three main characters explore the headquarters of "A.R.M.A.," the weapons manufacturer that created them. A mysterious incident has affected areas around the compound and has warped the city and buildings into a persistently shifting labyrinth. Utilizing their martial arts training and weapons they find in the labyrinth, they must battle their way past waves of biological weapon creations and fight their way to the core of A.R.M.A., where the answers to the mysteries lie.
