I'm stalled at the SAM turret and only last a few seconds before being wiped out by the drones. Firing seems to have no effect and "tracking" the drones with mouse look only produces a set of brackets around the targets in my viewscreen. Is there a "lock on" button that I don't have assigned in the control options or what? I don't see any corresponding feature listed in the control options that I could map a keystroke to either. I'm stymied and any help would be appreciated.
Thanks for the reply. Yes that's the level. I'm shooting the SAMs when the red brackets appear, but they seem to have no effect at all. Within 2 or 3 passes of the drones I'm dead meat. I can't even seem to destroy the ones closest to me as they're flying directly overhead. I guess it's a case of bad level design more than a lack of technique. Really frustrating since I don't get stuck like this very often since joining CH to get the most out of my games.
