So far, beating Relentless on COD WAW on veteran is my proudest achievement. But Heart of the Reich is what I'm stuck on. And Mile High Club is what I'm gonna attack soon.
Key to the City (PS3, 55 hours of playtime), Burnout: Paradise platinum trophy (still my only plat), and Dead Eye (Warhawk). I got the Warhawk trophy on a fluke like the guy in the article, when I wanted to see if I could do damage to a jeep with my sniper while he was driving away- I ended up killing the driver, lol.
Fable 2- i got the achievement for owning a real estate of 2.5 million gold. oh that and the Black Knight one. Where you have to shoot a hollow man in a specific order.
Oblivion-I got everything, 1000/1000 :D my proudest right there.
This one isn't really an actual achievement/trophy but I felt pretty proud when I discovered a glitch in Team Fortress 2 that let's you backstab people while invisible. And those people at EA are too lazy to fix the glitches on the PS3 version :D Also starting a PS3 clan. I'm not much for actual trophies :/
1-beating mile high club veteren
2-getting achievement for banjo kazooie on box live for 900 notes...it took me ages on n64 so im glad this time around i ot achievement for it
My best wasn't an achievement but a challenge on CoD4 online. I got the What The? challenge. You have to shoot an explosive device through a wall to kill an enemy, man that was solid
The Achievement which im most proud of has to be 1000G On Avatar TLA TBE. i spent about 3 hours trying to get those achievements. they were bloddy hard.
Vidmaster: Annual on Halo 3, playing with only one other person who knew what the fuck they were doing. The other two were complete shit, and made the whole thing take about 4 hours.
