Armored Core 6 introduces a thrilling Arena mode that pits players against formidable enemy ACs (Armored Cores). This comprehensive guide outlines the unlock prerequisites and valuable rewards associated with each Arena opponent.
Unlocking these adversaries is intricately linked to your progression through the game’s narrative. The initial Arena, featuring 29 opponents, gradually becomes accessible during your first playthrough. In the subsequent playthrough, New Game+, you’ll unlock the second Arena comprising 12 opponents. The final trio of opponents, however, is exclusive to New Game++, reserved for your third playthrough. The last of these adversaries is unveiled during New Game++ > Chapter 4 > Mission 29-B: Underground Exploration.
Emerging victorious against all Arena Opponents isn’t just a feat of skill—it unlocks the coveted “Testing Complete” & “Master of Arena” trophy/achievement.
These combatants become available as you advance in the storyline and defeating all Arena Opponents will award you with the “Testing Complete” & “Master of Arena” trophy.
