I'd like to try that carpet bombing/dumbfire strafing again next week. Or earlier if we are all still around.
Dayrth, it looks like the game was working as intended. The installation might have been invulnerable to air attacks, but I took my SRV down there and completed the mission. I suggest next time we try we take a heap of SRVs with us. The more we can stuff in our ships the better. We use them to coax the skimmers out of hiding, and when they blow up by being caught in our own fireworks it's no great loss as we'll have plenty spare.
