prey demo has just hit the xbox live market place and i decided to review it. First off, you get to play as an indian boy who is fighting aliens who abducted him. You start off with a wrench and as soon as you beat your first alien u get a smg all alienized with a scope on it. You then find out u can walk on walls and start to enter wierd portals. Being the big draw of the game the wall walking and portals are fun, but i got kinda dazed when i was doing it in multiplayer, sometimes you will find yourself jumping and ending up on the other side of the map.Speaking of the Multiplayer, THE GAME LAGS SO MUCH. Its soo bad when your about to acid spray this guy and the game lags the guy across the screen. Going back to the multiplayer, midway through the demo you get a spirit form in witch u shoot arrows invisibly, its a nice touch to the game and puzzles revolve around that form, u can use this in multiplayer but i dont find much use for it. Overall the demo is worth the download and i will probably be getting prey once it comes out.
