I'm sorry that you've failed to do that, if you wished. The mechanics of the original game are straightforward, and there's no overt shenanigans like in TFTD. Be patient in the combats, don't bring any weapons that you will kill yourself with when you get terrified, and be prepared to lose a lot of fights and start again with a fresh soldier. It's doable. My limit wasn't imposed on number of interceptors, or on tanks for base defense. Just for offense missions. You can't afford to make a single mistake, but you can win it. Well, maybe; I did.
All one needs to know is that
aliens do not require sight for mind control, and all of your soldiers mind controlled = you lose the mission.
