Whats hardest acievement on xbox 360? For me its complete gears of war on insane and complete cod4 on veteran, and right now im trying to get the "mile high club" acievement on cod4.

go through an entire level without firing you gun or throwing grenades but you can use melee (cant remember the game or name of achivement)

i think that one is in COD5? and i just got the mile high club acievement!!!!!

woop yeah that one is hard i still havent done it

yeah it is cod5 and i did that the second day i had the game. just pick the game with the less firefights or somethin and do it with only your knife.

Get Platinum in every event on Prototype. Using analog sticks to rotate the camera and character make the movement events almost impossible.

"Welcome to the Animus", Assassin's Creed. Impossibubble. :(

thats one is the hardest =p

Yeah the Gears Of War, beating all the levals in elite mode or somethin can't rember. But anyways I was playin with my cousin (Who's 11 and nevered played before.) I got scared on the third leval. You know the one where you have to get the monster outside and usin the hammer of dawn. But yea could of beatin it. (Maybe.) But also me and brother almost beat it a long time ago then we had the three rings of death. So we threw it out. :P It fuckin sucked.

I remember that monster, scared the shit out of my friend and I when we first played it. Good times.

I have to agree with Awesome on that one its flippen hard!

it took mee 4 weeks to get the mile high club achievement

Ya I am still no where near that one either lolz

when you figure out how to get the " Mile High Club" acievement, its really really easy, got mine after like 5 tries i think. i took me two hours before i figured it out through =p

I think its pass gta4 in 30 hours ahaha u have to stay up all day

Vidmaster achievement, Halo ODST,  4th set in heroic. 

Its definitly beat gta4 in 30 hours cuz its so dam long and the only way I saw someone do it was swtiching players half way through. 1 guy did fifteen hours then another did the last 10

Im not sure about hardest but the most stupid achievement is def in fifa10, quit 5 xbox live games and you get an achivement with 0g. One of the secret ones i read

Getting an Xbox that won't RROD on you. ;)

fanboys, there always about the place
