Street Fighter IV for the iPhone and iPod Touch has very few cheats for a game built on special moves and powers. That being said there are a few things you can do to liven up the experience.
Unlocking the character DeeJay can be accomplished by fighting in 3 Versus Mode matches (which are the multiplayer matches the game supports) or by clearing Tournament Mode with every single character while having the number of rounds set to 3 or more. That way is certainly not the easiest task in the world to accomplish.
To unlock Survival Mode, which allows you to continue playing over and over with one health bar until you die; you need to complete the Dojo Mode. After doing this, playing Survival Mode will give you the “Congratulations” screen.
And as far as we know, those are the only two cheats or “unlockables” in Street Fighter 4 for the iPhone and the iPod Touch. If you know of any others, please share using the comments below.
