Combat-focused addon for Krastorio 2 Spaced Out, adding new ways to fight back against tougher enemy modpacks such as Rampant Fixed, Fulgoran Enemies, and similar combat expansions.
You can add "Two More Turrets" separately to your save. I did a quick test and it seems to work fine with K2SO Arsenal.
One thing to keep in mind: while K2SO Arsenal is enabled, you won't be able to edit the stats of the Heavy Gun Turret through that mod's settings, and I don't currently plan to add support for that option, for reasons of balance.
Also, the Cannon Turret from that mod may still have friendly fire issues, despite my patches.
