I got my copy and beat it in two sittings. It's pretty much like Super Metroid but in an Aliens/The Thing setting. As said above, it cannot possibly compete with Super Metroid, and while it doesn't reach the heights of that game in any area, it's still an enjoyable game and does what it sets out to do just right. The manual is quite immersive and the story-telling with cutscenes are welcome to break up the gameplay a bit. Overall, I'd give the game 6 or 7 out of 10. A longer game and more originality and it may have become a classic. Looking forward to the sequel.
