Expansion Slot Unlocks

Discover how to unlock all expansion slots for your Armored Core in Armored Core VI: Fires of Rubicon. Learn about mission requirements and upgrades to fully customize your mech.

Expansion slots in Armored Core VI: Fires of Rubicon are crucial for customizing your AC with various parts and upgrades. While the game doesn't explicitly have 'expansion slots' in the traditional sense, the ability to equip more parts and upgrade your OS is tied to your progression through the game and specific achievements.

Key Progression Points:

1. Early Game Customization: As you progress through the initial missions, you will unlock more AC parts and weapons. Experimenting with these in the Arena and during missions is key to understanding your preferred playstyle.
2. OS Upgrades: The 'Tuning Expert' trophy (Gold) is awarded for performing all OS upgrades. These upgrades enhance your AC's core functions and effectively act as unlocking more 'slots' for performance improvements. This is achieved through consistent gameplay and completing missions.
3. Arena Progression: Clearing all Arena programs, as indicated by the 'Master of Arena' trophy (Gold), unlocks further customization options and demonstrates mastery over various combat scenarios.
4. Mission Completion: Simply playing through the game and completing missions will naturally unlock a vast array of parts. The 'Hardware Engineer' (Bronze) trophy for assembling an AC and 'Software Engineer' (Bronze) for upgrading your AC's OS are early indicators of this progression.
