Five Hardest Achievements to Unlock on the XBOX 360
Five of the hardest achievements to unlock on the xBox 360.
1. Grizzled Veteran 150g – Call of Duty 3

This is one of the hardest for two reasons, one being that it IS insanely hard but the other being that it is a terrible game. I know the Call of Duty 4 campaign can be frustrating making you replay a part over and over again on veteran, but you are able to do it; however Call of Duty 3 itself is such a poor game you don’t want to play it once, never mind hundreds of times. This campaign is Impossibly difficult on Veteran. Also annoying is, if you don’t play the campaign all the way through in one go and do it a random mission every now and again you won’t get the achievement.
2. World Champion 40g – Ghost Recon Advanced Warfighter

Really is a 1 in a million achievement as to get it you have to top the World Wide Leaderboard, has been described as like trying to ‘kick down a skyscraper with your feet.’
3. Seriously 2.0 50g – Gears of War 2

Anyone remember seriously from Gears of War get 10,000 kills, well how about this time you try and get 100,000; a big time consumer which is the reason this achievement is hard.
4. Brass Balls 100g – Bioshock

To do this you have to beat Bioshock on the hardest difficulty WITHOUT DYING. However there is an option to disable the Vita Chambers so when you die you just go back to your last save point but still a challenging achievement.
5. The Inhuman Achievement 15g – Guitar Hero 3

Beating a song on Expert that even Dragonforce, the band who wrote it, can not do. Is it worth just 15g and then to have all those notes from the intro tapping section endlessly playing in your head? is it really?

wow these r hard
Brass balls isn’t all that tough to get given Bioshock’s save system where you can save whenever and wherever you want (cept the final boss fight). Replace that with “Mile High Club” from COD 4
Mile High Club isnt even that hard ‘No Fighting In The War Room’ is harder. I realise now that Brass Balls isnt too difficult beacuse of the save system. I will look for one to replace that
not an achievement but the halo 3 mythic recon challenges.
They are extremely hard to do.
Maybe impossibly hard to do
NO
they can be cheated anyway some people will go in to rumble pit and cheat them with guests and friends, achievements like the killtacular one can be cheated this way, who would do that, WHO? I admit theyre not easy but easy cheating them makes them detract in hardness
actually the gears of war achievment is easy because it doesnt matter what difficulty your on so its really just time consuming, not hard.
To get SERIOUSLY 2.0 you just have to do the one where you ride the Brumak over and over again.
The Halo mythic ones are easy because Killtacular, extermination, and a few others can be gotten in GRIFBALL! Save this film just go on social slayer and hide and pick people off.
No no no no, you guys. Antony was talking about The Vidmaster Achievments for Halo 3, which are 7 tough challenges you need to complete to unlock a special armor. They’re not all that had, you just need good teammates and lots of time, usually around 3 hours (which was the hardest part for me).
