Just started Classic with Ironman enabled and damn that's HARD!
Additionally i encountered a bug which cost me 3/4 of the team
Had to evacuate a VIP.. mission goes well and the VIP is dashing to the pickup zone. I let her dash the final distance while an alien is near her figuring the mission is over safely.. wrong.
The camera freezes up on the spot where she entered the safe zone, couldn't pan across the battlefied anyome and the lone alien proceeds to slaughter my squad until my last man got him!
So beware.. clear out all aliens before you evacuate
