Krastorio 2 buffs the vanilla gun turret: range goes from 18 to 25, and Physical projectile damage research gives it bigger bonuses. The Heavy Gun Turret mod doesn't account for this. Its turret ends up with less range than the regular gun turret it's crafted from, and on most research levels a smaller damage bonus too.

This mod fixes both:

• The heavy gun turret gets the same range as the gun turret (25 with K2).
• On each Physical projectile damage level, it gets whichever bonus is higher, its own or K2's gun turret one. It keeps its +30% per level on the infinite research.

Both changes can be adjusted in the startup settings. You can turn off the range change, or have it copy K2's gun turret bonus exactly.

Works with Krastorio 2 and Krastorio 2 Spaced Out. You can add it to an existing save, and the research bonuses get recalculated on load.
