I was excited when I saw the first few articles about the new game, now I'm disappointed.
The scariest thing about a Sectoid is their expressionless childlike appearance, big heads and eyes. I've noticed in most of the game informer articles that they are chimp like now, squatting with pot bellies.
In the original, even with their pixelated selves they still manage scare the hell out of me, walking into an alien ship piercing the darkness and seeing five humanoids looking back at your soldier with only 29 TU's to spare is truly priceless.
I've had times where a Sectoid would STAND in a field of grass waiting for me to move the spotter and when I do it would ease around the map and kill a soldier from the other direction popping out of nowhere.
Somehow the new aliens managed to create very advance technologies and genetics; travel hundreds of light years, to step out of their ships with a bad back problem.
Sectoids created all other aliens; they think as one, they are the hive. I thought the mission was to change their sexless species through advanced genetics, maybe the new mission is to splice in chimpanzee DNA.
Update them, but leave the human like characteristic of standing on two feet alone, just make more aliens.
