Read this and weep, "Killzone 2" fans. This is no trick. I have completed 6% of the game without playing a minute of it! Or so my PS3 thinks. No, you do not get 6% credit for simply putting the game's disc in the PS3. Instead, this is a weird side effect of me having completed the game using a pre-released edition of the game, earning Trophies for it, but apparently not having my stats or save files transfer over properly.
