It's an interesting game, but currently in a very rough shape (which is why you can't even buy it via Steam).
However the setting of the game comes out a bit silly at times, especially since the gameplay ends up focusing on stealing scientists from other nations while preventing them from doing the same to you.
That makes it sound like Ice Station Zebra.
