Silent Line: Armored Core

Silent Line: Armored Core, known in Japan as Armored Core 3: Silent Line[a], is a 2003 third-person shooter mecha video game developed by FromSoftware for the PlayStation 2. It is the seventh entry in the Armored Core series and a direct sequel to 2002's Armored Core 3. In 2009, Silent Line: Armored Core was ported to the PlayStation Portable.

Some time after the liberation of the underground city Layered in Armored Core 3, mankind has begun reclaiming the surface. The corporations explore the world and expand their reach, constructing factories and fortresses on the new lands. While exploring the planet, several teams vanish behind the border of a mysterious region known as the Silent Line. The player takes the role of a newly-registered Raven who must unravel the secrets of the region.

Gameplay in Silent Line offers incremental feature updates to the franchise, namely the addition of player-trained computer-controlled versions of the player's Armored Core and a first-person view. Otherwise, the game retains its core structure of customizing mechs, taking on missions or fighting in the Arena, and multiplayer versus modes.
