Scorched Earth
Background
This mission is to be a simple supply depot destruction mission.
Walkthrough
You only have the same story-immune Alpha Wing on this mission, with either the Perseus, Myrmidon, or Hercules Mark II. Just pick whatever's good for defense.
Wait, no supply depot? Really?
All you have to do is just defend the Lonewolf against multiple waves of Hercules, Ulysses, and Loki fighters.
Then the Argo-class Arbiter will come in, send two team mates to defend it. After it leaves, just defend the Lonewolf for a few minutes and you can take off.
