For me it has to be all platinum awards in PGR3 or any achievement i've made on geometry wars
ive got the survive one i think, got it on my first attempt.Trousers said:My Zero Hour Achievement. HA.
Seriously though it would have to be completing CoD2 on Veteran. Getting the last two achievements in Geometry Wars will eclipse even that though if I can manage to nail them (Survive 1m and Quartermaster)
