Finished a run through classic, went by really quickly. After building the hyperwave station, why wait? I wasn't delayed by research progress and resources were piling up. And I had tried out most things on my first playthrough... I only regret not trying drone capture, I had the ability for some 3 missions? Opportunity didn't come up. It would take serious balls to leave a sectopod unharmed when you're that close, to zap a drone instead. Stats:
190 days
30 missions
1 country lost. This was out of my control, happened in the first 2 months.
Average shot: 73% Happy about that. Patience, grasshopper!
Days until second satellite: 20, third in 36. Nigeria bailing out really was out of my control! I bet the 4th went online 36 days out as well, because that must have been the day my second uplink finished construction.
Anyway, we talk strategy all the time, so I won't make a huge post out of it... but a couple of thoughts on higher difficulty stuff:
-Learn to move in a way where you're only facing 1-2 groups of enemies at a time and you're the first to draw blood. Danger escalates exponentially when the number of bad guys grows on screen or the number of fronts you're fighting on goes up.
-Always be flanking. Flanking someone isn't always represented well on screen, so look at that diagram someone posted earlier if you have to. If you're moving from point a to point b to only close distance between you and the target, you're doing it wrong.
-Cryssalids never stop being scary. Even though reaction shots will pick a lot of them off and they're one shotted by everyone later in the game, spooky stuff! A lot of the really powerful aliens don't make this impression. Not their fault, but when a sectopod or an ethereal saunters on screen, they get the undivided attention of 6 soldiers. They're toast.
-Take care of your snipers. They're your get out of jail free card. A sniper with squad sight, double tap and a plasma gets first priority, before assaults with ghost armor and alloy cannons, before anything really.
