Mine is from Left 4 Dead. It's the Man vs. Tank achievement, man that was hard!

Has this not be done recently ? Anyway, Architect in CoD, that fucking sniper pissed me off >.>

Too many to go through, but the most recent one would have to be finally beating Guitar Hero III on Expert, or maybe beating Charlie Don't Surf on Veteran.

Dude, that was kinda easy... sorry.

Mine is also an L4D one, it was Stumach Upset and I am sooooo close to getting Zombie Genocidest.

My ass. :D
/thread.

On topic: That would be Zombie Gynecologist Genocidest

I got Man vs. Tank on accident. Seriously, I molotov'd a tank right as we hopped on the boat. As the game stats are rolling, suddenly I get "Man vs. Tank" achievement.

mine would be Master of Statesman's Task Force from City of Heroes. It's already amongst the hardest challenges in the game, and to get that badge you have to do it without any deaths (on a team of 8) and under 2 hours (which isn't that hard). I've seen many teams fail the task force entirely, or have the entire team wipe 10-15 times during the task force.

That, or beating God of War on the hardest difficulty.

Mile High Club on Veteran (Call of Duty 4).

Christ, that was hard. I'm also quite happy that I did an enormous fluke on Cr0wnd, the day I got L4D, and none of my friends had it the achievement yet.

Call of Duty 4 'Mile High Club' and 'No Fighting in the war room' on veteran, the latter because you have to do upstairs, then downstairs in those awequad angles, without a checkpoint and in one go...

Probably Gnome Grinder in Overlord 2. I had to destroy one thousand of the little bastards.
