Armored Core 6 (VI) features an Arena mode where you can fight against enemy ACs. This guide lists the unlock requirements and rewards for each Arena opponent.
All of them are automatically unlocked from story progress. The first Arena (29 opponents) unlocks gradually throughout the first playthrough.
The second arena (12 opponents) unlocks during New Game+. However, the final 3 opponents are only available in New Game++ which is the third playthrough. The last one will become available in New Game++ > Chapter 4 > Mission 29-B: Underground Exploration.
Defeating all Arena Opponents unlocks the “Testing Complete” & “Master of Arena” trophy / achievement.
Missable Warning: The last 3 Arena Opponents disappear after finishing New Game++ (3rd playthrough). Make sure you defeat them before this.
