Top 10 Hardest Achievements in GamingAchievements date back as far as the Xbox 360 era of gaming. They help inspire gamers to keep playing the game or to play it in a certain way. A lot of them are quite easy and almost impossible to NOT get, but then there’s the ones that are absolutely backbreaking and will truly put your skills to the test.
All you have to do for this achievement is to play on the same server as Garry (the creator of Gmod). Immediately, you think that you can just friend him on Steam and join the game when you see him online, but it's not that easy. Garry doesn't accept friend requests, and he hardly plays the game anymore (or at all). All you can do is stalk his profile and hope you catch him playing the game. Aside from that, this achievement is almost impossible.
What makes this achievement so hard is that there are no instructions on how you can obtain it. Many players have obtained it at random or have found out the secret to getting it, but with every patch, it was changed. The developers truly wanted this to be unachievable.
For this achievement, you have to be #1 on GRAW's global leaderboard. Basically, you have to be the best player in the whole world. That's thousands upon thousands of hours of gameplay. Not to come off as rude, but you have to have no life whatsoever to achieve this.
This achievement asks you to survive 7 in-game days in infinite mode. That's roughly 14 hours of non-stop gameplay you're looking at. Probably best you reserve a weekend for this one.
You must beat Halo 1, 2, 3, and 4 on Legendary mode, with all the difficulty-upping skills on. This achievement will be trial and error and will determine how skilled you truly are.
Similar to War of the Worlds, you need to complete the entire game within a very tight time limit, in one sitting, without ever saving or dying. To make matters worse, you can't even attempt this until you've beaten the game twice. Hardly even worth it since all you get is a silver trophy/10 gamescore.
This game is known for being incredibly hard, but this achievement is even worse. You must beat the game in one sitting WITHOUT DYING ONCE. Have fun suffering.
This achievement requires you to complete Rock Band 2's 'Endless Setlist 2', which contains nearly every song in the game, without ever failing or pausing. Good luck on getting this one.
To get this achievement, you have to beat the entire game without getting hit once! If you've played Mega Man, you'd know that you get hit a lot throughout the game, making it one of the hardest in the series.
For this achievement, you are required to win 100 fights, complete 100 fatalities, perform 150 x-rays, and spill 10,000 liters of blood WITH ALL 28 CHARACTERS. This achievement isn't so hard as it is time-consuming, but it's still a pain to earn.
