OK, IF you have played Diablo II, and you are expecting to get a similar satisfaction from this game, don't try it. Better go buy Torchlight II.
First of all i must say that i got this game in a bundle for free, not even with that i managed to like this game. I wanted to like it because, c'mon, is you vs lots of monster aliens to kill. But the flaws are just to much for me to even enjoy it.
First, the curiosity is what makes you play the first levels. But after a while, you realize the game is just walk-kill, and is not even that rewarding, most of the time you will get items you can't even use, and most of your money will be spent in repairing. And when you got the money, there is actually not much to buy. There are not many weapons.
The mechanics of the technological weapons are not explained at all. And that reminds me, the interface is... not really good. You will be guessing what all those numbers and symbols on screen means in the first 40 minutes of play.
i didn't get as far as 3 biospheres or whatever they are called, not a single boss. Pity.
The mouse interface is a pain too, sometimes you will be fighting to get a tiny pistol or med kit that was droped on the floor. And that reminds me that if you are not carefull, you will be missing some items on the floor because they are hard to spot most of the time, i wish the had left the "alt" key as a toggle key.
No stashes, no place to keep things stored, no secrets or hidden places.
Story is not good, if there is any.
Music goes with the mood of the game but is not good either. i belive there is only two background music pieces.
After a while of playing it, you will be playing with some kind of strategy using run/walk, hiding behind objects to ambush the aliens coming for you, but after a while of doing it, it gets awfully boring.
I know the developers put a lot of effort in this game, it can be noted, but is just a big "no" for me. The graphics are probably the best thing here. And for me, thats exactly the problem. It lacks good gameplay, good story, good music, even good ambient, i didn't feel inside a spaceship, neither a biodome.
If you don't give a damn about the things i mentioned, and just want good graphics (for 2005) and just go around maps killing everything at your path and destroying objects to complete your missions, feel free to play it. I strongly advice playing a demo, or looking at gameplays before buying it.
If you care about any of the details i mentioned, you won't be able to play this game a lot, is just plain boring and repetitive, no surprises, no misteries, just go around killing. Once again, if you played Diablo and you are looking for a similar experience, go for Torchlight II.
