How to find new parts in Armored Core 6

The best way to find parts for your AC unit upgrades is to play through the campaign. You are rewarded with various parts for your progression through the game by completing main and side quests. This progression helps you maintain your unit’s strength to match the increasingly difficult enemies you encounter in later chapters.

Finding Armored Core 6 parts through exploration

Although there are many parts you can easily find through campaign missions, Armored Core 6 has many hidden parts that are totally missable. These collectibles are found in Supply Crates scattered throughout the map. Since they are hidden parts, you have to go out of your way, often through some secret path, to obtain them.

Luckily, you can use your scanner by holding down on the D-pad, which shows the presence of any containers in the area.

You can find the breakdown of all the hidden parts locations in each chapter of Armored Core 6 below.
