• Testing revealed that as a level before 2-4, even with all Choice 1 options selected, players would most likely need ==Defense Bombs== or ==selling base HP== to clear it — a clean run with Choice 1 was nearly impossible.

• ==Difficulty has been reduced== for this level.

## ⚠️ Known Issues

**Skirmish 2-3 Aircraft Mod 3 Audio Distortion**
