yeah, i got the gigawatt powerblade also, i (pre)ordered it on my local gamestop.
nothing special with it, it just makes you, a one-hit melee char lol.

be sure to input the code after "installing the game", (running the game once) or you will have to redownload it.

also got the uncharted 2 mp beta voucher.

i'lll be playing it tomorrow on all my free time after work. damn work /cry XD

hopefully, i can finish it before my cross edge get delivered.
