Think I'm about to hit a wall in the difficulty curve. Sent a Skyraider to a UFO landing that served as the introduction of Elite Mutons and those bipedal robots.
Took sooooo many attempts to clear that mission, there were two robots right on top of each other, couldn't get near them without the pair of them decimating everyone. Eventually devised a strategy where I just crawled around the map, kiting out Mutons, Elite Mutons, Heavy Floaters, and Outsiders, occasionally sniping one of the drones that would come out from time to time. Then, once everything else was dead, gradually creeped up on them and whittled them down.
Without my sniper in Arcangel armor + plasma rifle + Damn Good Ground + Double Tap, I don't think I could have cleared it, let alone bring everyone home alive.
Love this game.
