Critical warnings

Important

BepInEx 5 (x64) required - install BepInEx before this mod.

Note

Laser-guided weapons skipped - AGR-18/AGR-24 use vanilla dynamic arc; this mod draws arc for non-laser missiles at minAlignment.

BepInEx 5 plugin for Nuclear Option: draws a launch arc circle on the Flight HUD for non-laser missiles when you have a target lock, matching the game's OUT OF ARC limit (TargetRequirements.minAlignment).

Laser-guided weapons (AGR-18 / AGR-24) are skipped — vanilla already draws the dynamic arc circle.
