Prey manages to re-invent many of the lost aspects for a FPS though it leaves room for wanting more
Gameplay: Prey's gameplay is not revolutionary but it is original and deviates from the traditional FPS through its physics tweaks and portal system. The level designs are great and allow the character to immerse themselves. Additionally, the games story was executed well. There are no points of confusion where you would get lost and it always seems to flow smoothly. Another apsect I like is that the character actually talks while you are in-game. This makes the player feel more connected. Lastly, since I dont want to include spoilers, I do enjoy the various parts of the game where you have to think and also the various twists.
Graphics: Many of you know Prey uses an extremely modified Doom 3 engine. There is nothing wrong with this, I was just people know. Anyways, the Graphics are exceptional. Every item is finely detailed adding to the sense an actual place. The level-design though does tend to get repetetive in some of the levels but as I said before, the way the designers changed the Physics etc, it is not that big of a deal.
Sound: The sound in Prey is top-notch though some sounds seem a little cheesy but its nothing too extreme. Voice-acting is outstanding and it what helps to constatute a much better game.
Misc: I didn't play MultiPrey yet but from what I have heard, it is not too great. It seems it was the basic MP and nothing special was included..
Overall, Prey is a game that everyone should at least try before they buy. The demo version will leave most wanting more since the AI is comepletely dumb-founded but I assure you this dilema is corrected in the Final release.
The game could have been better as it was in developement for 10 years and certain aspects like portals, wall-walking and spirit-walking could have been used in much more innovative ways.
