Sequel to X-COM:UFO Defense, supposedly takes place underwater, yet oddly everything seems act in an identical manner. From what I've played so far, every single weapon, ship & alien is identical to the original, except for the different graphics and names. For example, in UFO Defense you would have a rifle, in this a harpoon gun. Instead of a rocket launcher, there is a torpedo launcher. Everything is the exact same. This game is a very thinly concealed attempt to milk to X-COM franchise for all it's worth.
