The artwork was cooperatively designed by Soulcalibur artist Takuji Kawano, Kazue Saito of Super Robot Wars, and veteran artist Kazunori Haruyama. Development began in 2003, directed and written by former Banpresto staff member Soichiro Morizumi.
The project was proposed by Monolith Soft to celebrate Namco's 50th anniversary, and Capcom was contacted as a partner due to their large character roster. The narrative sees original characters Reiji Arisu and Xiaomu, operatives for paranormal investigative group Shinra, confront distortions bringing characters from other realities into their own. The gameplay combines tactical RPG and action sequences during battles, featuring characters from video game series owned by Namco and Capcom. Namco × Capcom (pronounced as 'Namco Cross Capcom') is a tactical role-playing (RPG) crossover video game developed by Monolith Soft for the PlayStation 2 and published by Namco in 2005.
