another question: how does target lock work? do i just [space] when the enemy is in my hud with the square, or do i actually have to track him?
Its like the original. Use the +thrust key. When its 100% press once to activate afterburner (goes yellow) press again to disable.
Target is just pressing T which will cycle through the targets (see key map on the page). Note: If you are playing locally, the debug info is available - it is not available on web (only portions of it)
