Spoilers for Mecha Ace
So both times I played mecha ace, I got Hawkins good ending, but my lance squad died in chapter 7(I was able to save cloud base) so I wonder its it possible to save your squad and get Hawkins good ending. I though since your CO mention that they were missing and their is a rare chance they survived, that they will appear in the final episode but no. So if anyone of your house could help that would be great
