Armored Core VI: Fires of Rubicon is FromSoftware's return to its mech action series, ten years after the previous numbered entry — a third-person action game where you assemble and pilot fully customizable combat mechs (Armored Cores) in high-speed aerial combat across the resource-rich world of Rubicon 3. It is a reboot of the series, released on 25 August 2023 for PC, PS4, PS5, Xbox One and Xbox Series X|S.
The assembly system is the game's defining feature. Every component of your AC — head, core, arms, legs, boosters, FCS (targeting), generator, and expansion — affects combat performance across dozens of stats. Four weapon slots (left arm, right arm, left shoulder, right shoulder) hold your arm and back weapons, within the limits of the AC's weight and energy. Matching the build to each mission means balancing weight, energy and combat style.
Combat is aerial, fast, and three-dimensional. Assault Boost charges enemies aggressively; Quick Boost is a fast evasive boost; the Stagger system lets you build up an enemy's stagger meter to open a window for extra damage. Online, the game offers PvP only (1v1 and 3v3); ranked matchmaking was added after launch, per Wikipedia.
Every AC component affects combat performance: head, core, arms, legs, boosters, FCS, generator and expansion all change your stats.
