I did win a mission like this by destroying the centre, I think. I had covered most of the base with my soldiers and killed a large number of aliens. I had a single rocket tank in the centre of the base. I opened the large door, proceeded like 1 tile forward and it saw aliens upstairs. I shot them with the rocket tank and there were several explosion in a cyclical pattern, mission ended there. I am not 100% sure though if it ended because of destroying the centre or if those were the last aliens in the base. :crazy:
One question guys, how do you know in advance that a spaceship or a base belongs to certain alien species? Is it something obvious that I haven't noticed or is it that you know after you have attacked them with ground forces?
I always play without reloads now and I find it very exciting and you are truly worried as to what might happen to your soldiers. Also you tend to follow better tactics and covering behind anything, from trees, to bins to furniture etc. It feels so realistic!
