Mine was when I beat Left for dead on hard cause you have no idea how hard that game is. Also another one I'm proud of is kill 50-100 alien things with the force gun?
Played every game in the PS2, Wii, 360, PS3 and PSP up to date.
Hmph talk about lying... And that's the video game section,not the flash one by the way
I'd say...The 740K of dammage I've done in phantom Brave with a Cat bearing a trout.(Sounds random?Yeah...I play bizarre game,thanks To Nis!!!(Nippon Ichi Software))
I was so excited when I got my first Killing Frenzy on Halo 3.. but I'd have to say when i got the "AN-I-MAL!!" achievement for Rock Band haha. It's the achivement for beating the world tour on expert drums.
I beat Gemcraft over the course of about 5 days, and got all glowing frames before the last epic level, and on all the hidden levels. I got a glowing frame on the last epic level in one try.
