GI JOE : THE RISE OF COBRA CHEATS
(Pal) AND (NTSC) Submitted by Barney STIN50N
At the Press Start screen input the following :
Classic Duke: D-Left, D-Up, X, D-Up, D-Right, Y
Classic Scarlett: D-Right, D-Up, D-Down, D-Down, Y
Once input correctly you will get a "GI JOE" yell.
Don't ask me why but these 2 make it SOOO much easier to get GI Joe rank on each level. Multipliers show up a lot more for some reason. I found these out halfway through the NTSC and instantly noticed the difference. When I came to do the PAL version I got GI Joe rank on every level first time through.
Also For some odd reason if you complete a mission with Duke and Classic Duke you will get the achievement for playing through a level as Duke and Baroness. (Lovers Quarrel) But if your going for the full 1000 this wont make a difference as you will have to get every character anyway
