About AC6 S-Rank Calculator

This Armored Core 6: Fires of Rubicon S-Rank Calculator helps you determine your mission ranking based on your performance statistics. The ranking system in AC6 evaluates multiple factors to determine whether you achieve S, A, B, C, or D rank for each mission.

How Mission Ranking Works

Armored Core 6 uses a complex scoring system that weighs several performance metrics. Understanding these factors is crucial for achieving consistent S-ranks and unlocking the "Perfect Mercenary" achievement.

  • Completion Time (Highest Priority): The most important factor. Faster completion times significantly improve your rank. Each mission has specific time thresholds for different ranks.
  • Damage Sustained (High Priority): Shown as "Repair Costs" on the results screen. Lower damage taken improves your rank. Using repair kits doesn't affect this - only total damage matters.
  • Enemies Destroyed (Medium Priority): More enemies defeated generally improves your rank, though this varies by mission. Some enemies are worth more points than others.
  • Ammo Expenditure (Low Priority): Shown as "Ammo Costs" on results. This factor is usually lenient unless you significantly overspend on ammunition.

S-Rank Strategies & Tips

🏃‍♂️ Speed is King

Focus on completing objectives quickly rather than destroying every enemy. Use assault boost and optimal routing to minimize completion time.

🛡️ Damage Minimization

Avoid tanky builds that rely on absorbing damage. Use agile mechs with good defensive capabilities and positioning.

🎯 Target Priority

Destroy enemies along your optimal path to objectives. Don't go out of your way unless they're required targets.

🚫 No Checkpoints

Restarting from a checkpoint automatically caps your rank at A. Complete missions in one continuous run for S-rank eligibility.

⚡ Weapon Selection

Use multi-lock weapons like plasma missiles for efficient enemy clearing. Twin shotguns and pile bunkers excel against bosses.

📊 Mission-Specific Requirements

Some missions have unique S-rank requirements like protecting escorts or destroying specific enemies. Check mission briefings carefully.

Advanced S-Rank Techniques

Master these advanced strategies to consistently achieve S-ranks across all missions:

Optimal Build Strategies

  • Reverse-Joint Legs: Excellent mobility for most missions, especially those requiring vertical movement or boss fights.
  • Twin Zimmerman Shotguns: High damage output for close-range combat and boss encounters.
  • Plasma Missile Launchers: Multi-lock capability makes them ideal for quickly clearing multiple enemies.
  • Pile Bunkers: Essential for high-damage melee attacks against heavily armored targets.

Mission-Specific Strategies

  • Boss Missions: Focus on completion rather than perfect execution. Time and damage thresholds are usually generous.
  • Escort Missions: Prioritize escort protection over enemy elimination. Failed escorts often result in automatic rank reduction.
  • Timed Missions: Plan your route carefully and use assault boost extensively to meet strict time requirements.
  • Stealth Missions: Some missions reward avoiding unnecessary combat. Study enemy patrol patterns.
