From a different perspective, i did not like this game, although it is claimed to be icon of Fps.
First: The main character is mute(doesnt talk during the whole game), DAMN I HATE MUTE CHARACTERS I DONT KNOW WHO CAME UP WITH THE IDEA, but i hate them, i love ghost recon 1 and 2 and hitman, Gears of war. and a lot of other Fps with Talkative MAIN characters NOT some. For that it loses 1 point.
2nd: i started playing this game in 2009 so the graphics are not quite good to me, And the storyline is not so thrilling, although is rather interesting. The shooting is good but not the best. WHY DO PEOPLE CLAIM THIS HAS THE BEST SHOOTING ENGINE WHEN IT DOESNT!!!.
Have you people played call of duty or ghost recon. Those are real shooting engines with realistic shooting sequence. Not shoot in 1 point and get the bullets in that point 100 times. For that it loses 1.5 points.
3rd:The monsters are rather stupid, crab people WTH!!! are you serious??!! my friend is loser to actually think that CRAB PEOPLE ARE BETTER LOOKING THE GRUBS(GEARS OF WAR ENEMY SOLDIERS) come one !!!!THOSE CRAB PEOPLE ARE BETTER LOOKING AND MORE ENJOYABLE TO KILL yeah right............GIMME A BREAK U IDIOT(referring to my friend not intend to harm anyone else lol). enemys dissapointing for that it loses 2 points.
Then the rest is all good, This game did not bug me at all, well everytime i close it it says error on windows, but i dont care cause it still saves my game and never seen glitches or anything else.
i really dont need u to agree with me or not, As this game is not of my taste and some people too but MOST seem to like it and im cool with that.
