I have finished Ufo few times and I thought I go and play X-COM TFD...And you all are RIGHT it is a lot tougher than UFO but more or less the same

.I have question:How you actually upgrade your soldiers?I mean all my mens have 8 missions with OK and EXCELLENT rating and the best one has killed more than 15 alien but he is STILL ENSIGN!! :ranting: And other at lowest rank.They have quite good stats thought but it is diference between seaman with good stats and commander with good stats...So how actually does this system work? :blink:
