🛡️ Systems & Mechanics
Tech Tree System
Enhanced tech tree with tech point unlock costs
Fixed nodes not unlocking, incorrect display of unlock conditions and prerequisites
Canceling a tech node now recursively cancels all dependent unlocked techs and refunds their costs
Tech tree loading optimized to run at game startup
Added three tech nodes affecting Drill Rig construction costs
Overclock & Rebuild
Fast rebuild and overclock features fully configured with visual effects
Fixed overclocked resource buildings not updating UI production numbers and missing grid consumption
Removed core overclock; refined overclock display and logic
Plug-in System
Added plug-in icons
Same building type across different levels now shares level-1 plug-in bonuses
Combat & Damage
Fixed projectile penetration logic
Fixed weapon retargeting ignoring faction checks
Fixed abnormal attack speed on laser weapons
Increased Machine Gun Turret penetration (2/3/4 targets), max fire rate and cost; reduced firing arc
Increased Mortar Turret damage and cost
Reduced Photon Turret damage against shields and armor
Adjusted unit “Fractal”: added shield, reduced HP and attack
Unit & Collision
Improved collision so units are no longer knocked away by rebuilding structures; fixed buildings blocking path during rebuild
All units' hit radius increased by 1.5×
Increased siege unit HP, reduced movement speed
Pause & Results Logic
Fixed upgrade and salvage continuing during pause
Changed retreat flow: must go through results screen before returning to menu
Added “Restart Mission” button on results screen
Mission & Dialogue
Optimized mission and dialogue systems; mission objectives now check automatically on mission start, no longer ignoring completed ones
Updated dialogue window; added new unit notification feature
Performance
Added physics step locking mechanism: slows game speed under extreme load to preserve computation time
Significant general performance optimizations
Optimized energy shield display for lower performance cost
