i buy this game for xbox 360 for 10 euro or so and and i be expect a nice shooter without too much story and a lot of graphical violence . and well and frankly even with that expectation it disappoint me . first of all i want to say that i like the original idea of wallwalking and etc . it cóuld have be very innovative if it wasn not for the developer turn this game into a semi puzzel or platform game every once in a while . i say this a lot of time and i be gon na say it again while platformgames and shooter dón not mix and period . i like a challenge and but for example i be trap in one ( big ) level for a entire week before i find out that to progress in the game and i have to shoot a small electro tube somewhere on the wall . what kind of game logic be that . so if you want to complete this game and you find yourself stuck and the best thing to do be thus basically shoot at everything and hope it trigger a door or anything . it be not the way i want to play a game . the most innovative part of this game be the portal and and even though valve portal mod do a far much good job at this today then prey and it be a cool effect ( at least for sight ) . be it necessary . no . be it confuse . very much . most of the time when you enter a portal and you will flip upside down and or sideways in a way that it will leave you desorientated for a brief few second and thus very vulnerable to enemy attack even with the most elite shooterskills . the weapon be also not very great . every gun look like a cliché alien gun and complete with bright light and shiny texture . you have a sort of plasma gun and a gun that you can load up with elemental stuff like fire and electricity and cold . you also get a gun that fire what could be describe a a load of snot . well and do i need to say more . it a if the developer of this game weren not even try . oh and and you also get to play with the lamest and and i mean the lame main character in a shooting game ever . at the start of the game and the indian guy doesn not bother you much and but far in the game his whine about his girlfriend and his childish and furthermore simply dull one liner ( damn and it dark in here . a if i do not notice that myself sherlock . ) will probably tick you off and will leave you with no feeling for the main character at all . and some more bug represent some puzzle ( read represent annoy counterpart ) require a lot of piritpower to turn on switch and so and but if this run out and you will have no other choise then to kill yourself in order to get more piritpower ( and no and there be no spirit power ups in the level apart from a few ) . and if you do not have any bug grenade ( how original . ) or alien rocket ( sigh ) you will just have to reload a old game and try again . also and what be it with the graphic . i mean and the game on xbox 360 already look like it could have run fine on the first xbox ( and i be not kid there ) and but some image be just too dark . and i do not mean just dark and but pitch black . even a shitty lighter that your character can activate can not change much about that . so this pretty much sum up what it be while a failed experiment and hype with the now very popular doom 3 engine . if you want a innovative and exciting shooter and go play half life 2 ( again ) and or the new portal mod i mention earlier . do yourself a a shooterfan a favor and ignore the hype and just leave this game for what it be .
