Yeah I started a game where I roll with the punches, because I'll admit, when shit went wrong I'd reload. I'd like to justify it as "within reason", but its totally cheating, haha. So far so bad, 2nd terror mission didn't go so hot.
I played a lot of X-Com in my day, but I never became one of the dudes who can beat the final mission in 1 turn, with maxxed out mind control dudes. Laser Rifles, Heavy Plasma, and human intelligence are where its at.
