Turret XP

Turret XP makes gun turrets grow into named veteran defenders.

Install a Veteran Core in a turret and let it earn XP from real fights. As it levels up, shape it into the defender your factory needs: a long-range sniper, a rapid machine gun, a tough bulwark, or a brutal close-range brawler.

Veteran Cores carry a turret's level, upgrades, elements, name, and combat history. Move the core to a new turret when the front line shifts, or keep it on a trusted defender and watch it grow.

Highlights:

Only chosen turrets become unique, so ordinary gun turrets stay stackable.
Earn XP from damage and kill contribution.
Spend points on damage, shield, ammo productivity, shield-on-hit, regeneration, crits, luck, double shots, XP gain, and bouncing bullets. Brawler lists 10% Lifesteal as an innate specialization stat.
Pick specializations and sub-specializations with strong tradeoffs.
Feed fire, electric, explosive, or toxic resources into passive element ranks to strengthen elemental effects and combos.
Name favorite turrets and show their level above them.
Choose exact Veteran Cores from platform hubs for space-platform defenses.
Tune XP pacing in mod settings.

Changes In 0.11.3 (2026-06-18)

Changes

Rebalanced asteroid XP on space platforms. Asteroids now use separate runtime-global multipliers for travelling platforms and stopped or paused platforms, defaulting to 20% while travelling and 5% while stopped.
Asteroid XP no longer stacks with the separate platform non-asteroid XP multiplier, fixing the accidental double reduction introduced in 0.11.0.
Added an XP rate line under the XP bar when a combat XP modifier is active, with an info hover showing the compound formula for asteroid/platform modifiers and Veteran Training.

Bugfixes

Changed Veteran Training to boost newly earned combat XP instead of multiplying the core's total XP at display time, so removing Veteran Training ranks no longer lowers existing levels.
Migrated existing Veteran Core profiles once so their already-earned Veteran Training XP is preserved under the new award-time accounting.
