After you finish the Extra Ops mission in the PlayStation version of Metal Gear Solid: Ground Zeroes, you will be treated to a little trivia game where you can earn an extra goodie. Once you complete the Deja Vu mission on normal and answer each question correctly, you will receive the Solid Snake Polygonal character model. That’s kinda cool I guess, but the real prize is Grey Fox’s Cyborg Ninja costume you receive after you complete the trivia challenge on hard difficulty.
