Hi,
I just Pre-ordered Xenonauts and started a game. This looks really promising so far.
However, I could not finish my very first ground mission. I searched the entire map but could not find the remaining alien(s). I noticed that the UFO was placed at the northern edge of the map, so I could not get to its rear. Is there a door that leads inside the UFO? Is it possible that an alien was trapped in there and I could not get inside to kill it?
