The OIGAMI is an Arisawa back part that appears in Armored Core: For Answer.

Part DescriptionEdit

A very large grenade cannon that takes up both left and right weapons slots.

How to unlock Edit

To unlock this part, the player must complete Defeat AF Great Wall on Hard difficulty. Equipping dual Kojima rifles or dual Kojima cannons or Kojima weapon arms will make facing Raiden easier. Dual MOONLIGHTs also works well due to Raiden's low Energy Defense. Furthermore, on some instances Raiden will just fall from the detached section.
