Armored Core: Last Raven

The game has a branching campaign structure and the progression depends on the player's choices. This leads to different missions to play and concludes in one of six endings. The missions, which are prefaced with voice-over briefings and emails to read, are action-oriented and straightforward; the player usually has to either defeat a number of enemies in the open, visit indoor levels or survive against a single, powerful Raven. The most important part is the mech customization in which the player can tune the performance of the robot and exchange parts. For the first time in the series, the outside parts (e.g. the head or the legs) have locational damage and can be destroyed during missions - for example, when an arm is destroyed the player can't use the equipped weapon anymore. Between story missions, the player can visit an arena and fight against other Ravens for training.

The PSP version has a few additional parts.
