You will need 2 Controllers. And a profile with all of the achievements you wanna glitch and this is best done OFFLiNE which means not connected to XBL.

TuT

load up the spg profile on controller number1,

now load up training grounds,

now load up basic training. as it starts to load, now pick up controller number (2) push the center guide button then (x)

now pick up controller number (1) and sign into the profile you want the achievements for.

then on controller (1) when prompted that youo are not connected to live push(a)

now on controller number (2) push (B.)

It will kick you back to the main menu and the SPG should have worked.

Go take a look in the War journal and see if all the stats copied over.

Now all you have to do is simply do 1 of each of the achievements. Example: Kill 100,000 enemies simply kill 1 and seriously 2.0 is yours. Play 1 more match party like its 1999 pops after the match.
