I finished the prologue as well as the main campaign, but there's one thing I could never figure out, no matter what I did...
What is the T-shaped symbol in the HUD, around the center circle, when you have a lock on a fighter? It moves, I can't influence its position by rolling, I can influence it a bit by moving the ship around, but I just can't tell what it is exactly.
I checked the manual, I checked Google and I listened to what Kettle (?) says in the training missions, but it's not answered anywhere. I wish the manual was more informative on this one, as you find HUD explanations even for the most stupid things for example in first person shooters (this is your current ammunition, this is your health... and so on).
I guessed something like that too, but shouldn't this one totally change when I roll? Because my impression was that rolling doesn't affect it much. And that's why I couldn't figure out what it actually is.
However, maybe I was just unlucky when I tried and the enemy ship turned as well.. Could you confirm the orientation tee thing?
