Armored Core 4 is a 2006 third-person shooter mecha video game developed by FromSoftware for the PlayStation 3 and Xbox 360 consoles. It is the twelfth entry in the Armored Core series. Armored Core 4 reboots the franchise with a new storyline and new mechanics.

The game is set in the future where a great war has left the nations of Earth devastated and their respective governments have been taken over by corporations. Conflicts begin to break out between the corporations, who use massive combat robots, Armored Cores, to fight each other. The player is a Lynx, a name given to pilots of highly advanced NEXT Armored Cores.

Armored Core 4 streamlines many of the features of previous entries while retaining its highly complex customization system. Players take on missions from various clients in return for credits, which they can spend on unlockable parts and weapons. In addition to system link and split-screen multiplayer, players can engage in online battles with 7 other players.
