Armored Core VI: Fires of Rubicon is FromSoftware's triumphant return to their mech action series after a decade-long absence — 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's the series' most accessible entry while retaining the deep mech assembly and combat mechanics that made the franchise beloved.
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) accept hundreds of weapons across energy, kinetic, and explosive damage types. Finding the right build for each mission requires understanding the AC's weight, energy, and combat style as a holistic system.
Combat is aerial, fast, and three-dimensional. Assault Boost charges enemies aggressively; Quick Boost provides rapid i-frame movement; the Stagger system (build up enemy stagger meter for a massive damage window) mirrors the Posture mechanic from Sekiro. PvP arena battles and ranked online mode provide competitive depth for players who master the assembly system.
Every AC component affects combat performance. Head, core, arms, legs, boosters, generator — hundreds of parts create thousands of viable build combinations.
Build up enemy stagger with continuous fire and explosive hits, then deal massive burst damage during the vulnerability window — the Sekiro Posture mechanic adapted for mech combat.
Linear mission chapters with grade scoring and replay incentives. Each mission grades your performance — S-ranking all missions is a full challenge loop.
Online ranked arena battles pit custom ACs against each other in direct combat — the ultimate test of assembly and piloting skill.
