P.N.03

(Product Number Three) is a 2003 third-person shooter developed and published by Capcom for the GameCube. Set in a space colony compound, the game follows a female mercenary fighting against berserk robots. Gameplay focuses on defensive tactics and includes abilities that can be upgraded.

Directed by Shinji Mikami and produced by Hiroyuki Kobayashi, the game is part of the Capcom Five, a group of video games developed by Capcom Production Studio 4 to introduce new intellectual property. To avoid similarities with Devil May Cry and Resident Evil, the game designers emphasized defensive and rhythmic maneuvers and a "feminine" game world. The game was developed on a tight schedule in an attempt to offset Capcom's poor fiscal year.
