Upgraded Flamethrower Turrets adds four powerful MK tiers to the vanilla flamethrower turret, each with distinct green/blue/red/purple coloring and high-quality custom icons.

Key features:
- MK1–MK4 progression with increased health (800–2000), range (+4 per tier), damage multiplier (2/4/6/10), and reduced fluid consumption (2.5 → 1.0/s).
- New recipes using tungsten plates, tungsten carbide, superconductors, supercapacitors, carbon fiber, ammonia, quantum processors, promethium asteroid chunks, and cold fluoroketone.
- MK3 and MK4 must be assembled in a cryogenic plant.
- Technology packs for each tier now include space science packs; MK3 adds agricultural and cryogenic; MK4 adds promethium science pack.
- Recursive mask tinting ensures consistent custom coloring across all turret animations.
- Dynamic tech patch automatically applies turret-attack bonuses from refined fuels research to all upgraded flamethrower turrets.
- Fully compatible with vanilla flamethrower damage technologies.
- Requires the Space Age DLC.
