Dune Legacy 0.98.6.3 Released

October 25, 2025

Dune Legacy 0.98.6.3 is now available! This hotfix release addresses critical rocket turret damage issues and improves overall game performance.

What's New in 0.98.6.3

🚀 Rocket Turret Damage Fix (Critical)

  • Fixed zero damage bug: Rockets now apply full 30 damage to air units within blast radius (previously scaled to 0)
  • Hit rate improvement: 3.5% → 66-100% against ornithopters
  • Kill rate improvement: 0% → 66-100% (turrets are finally effective!)
  • Proximity fuse: Rockets detonate within half-tile of air targets
  • Extended lifespan: 5-second rocket lifetime for better pursuit

⚖️ Ornithopter Balance Adjustment

  • Speed increased slightly: 15 → 17 (after fixing targeting issues)
  • Still 23% slower than original (22 → 17)
  • Remains counterable but viable for harassment

⚡ Performance Improvements

  • 60+ FPS support: Game now runs smoothly at higher framerates
  • New menu option: "Limit to 31 FPS" for multiplayer stability or low-end systems
  • Optimized pathfinding: Reduced budget for better frame pacing
New FPS limit option in settings menu

  • Customizable: Adjust AI behavior in QuantBot Config.ini in your AppData directory
  • Unit stats: Modify unit/structure properties in ObjectData.ini

Note: This release may have over-nerfed ornithopters slightly - please provide feedback on the balance! The rocket turret fix was critical: previously, distance falloff was rounding damage to zero, making turrets completely ineffective against air units despite firing successfully.

Technical Details: The damage formula for air units was applying exponential falloff based on distance, reducing 30 damage to 0 at the edge of the explosion radius. This has been changed to flat 100% damage within the blast radius for all air targets, making anti-air missiles effective as intended.
