Optional Parts are a non-essential part of an Armored Core which was capability of giving an AC enhanced capabilities.


Various modular units which "plugged" into the AC's core, these parts had widely varying effects and could improve anything from turning speed to energy weapon damage. Each core had a limited number of "slots" into which these parts could plug into, and each optional part utilized a set number of slots, increasing based on the part's percieved power and usefulness.

In Armored Core 4 and onwards, Optional Parts were replaced with FRS tuning.
