i recently preordered the game and they gave me the e3 demo for it on disk and it looks awsome. Any trailer andy video u have seen it looks 10x better on a hd tv. Its way better than halo 3. im not going to ruin it for anyone who gets it on psn but its a pretty big demo so i can imagine it will be over 1g. So if u want the demo on disk and ur going to preorder it go to gamestop only they give the demo (supposively)

srry for double post but its not in lockstrafe and u cant change it so it might b kinda hard but u can hold r2 and L2 and it goes into lock strafe
