Hmm where to begin with this game, i suppose i'll just give my opinion and in short i thought it was awful.
The graphics are actually decent...not amazing but not at all bad... the environments look good....characters well....to put it nicely are horrible. The special effects are pretty good but get boring. I would give the graphics a good 7 out of 10 but purely for everything looking good other than the characters.
The sound is horrible, many times did the music associated with action come to life after the fight was over and even then the music is just hard rock which i personally don't like very much. Also the gunfire noise is awful like that of....actually i cant compare it to a game off of the top of my head thats this bad. It's truly horrible. As such id give the sound a 4 out of 10, its only redemption is that when the music score does come into synch with the action it is fitting and an adrenaline boost.
The controls are good and well implemented other than the fact that the LT is not used for ANYTHING! i had to look at the controls to verify this and its true it is not used other than in conjunction with the RT, this i thought was unusual oh and the aiming is just plain disastrous its not "free" like that of CoD or other top shooters and so its hard to get used to...at first when you do get used to it its still just plain bad.
The one up side to this game is that its fairly easy for achievements, for example you would get 450G for just completing the game but thats based on whether the finishing achievements are stackable, i.e completing the game on the hardest difficulty also grants the achievements for any easier difficulties. I would not know if that is true as i haven't completed the game yet. Also i got one achievement for pretty much skipping a cutscene, basically the cutscene almost counted as a mission. and so the achievements seem simple enough too, there are no collecting achievements either which is cool.
As a whole the game is pretty go....wait no...its just plain horrible, its good for achievements but dont get it for graphics or story theres is neither. Oh and a word of warning you have to save manually and it doesnt tell you about that too, this caught me out as i got to the first boss, died, then had to restart the WHOLE GAME!! so just a word of warning there. Hope this helped and enjoy :)
