I do meet the systems requirements for this Xenonauts. However, when I started the game, the main menu flashed with a black screen lasting several seconds. I cannot play the game like this. My system is Windows 7, and I have 2 GB RAM. I also restarted Steam, and it did not solve the problem. I also waited a couple minutes, it didn't work. I ran Xenonauts in a window, and not in a window. Nothing is working! My version is v20 Hotfix. I also uploaded a video on youtube to elaborate. Here's the link:
If the video is not working, just use your imagination.
