Hi, Myrrh is right, it is flawed, out of the three it is the three star. The massive alien battle at the second battle in the game is a little much, and you will be lucky to survive (very lucky-save a lot). If you can make it past that battle, the game gets a lot better after that. It is still a fun game. Buy all three, on sale of course, and play them all. I enjoyed all three, but this one has ups and downs.
