As you look around on the first screen when you enter the game, there is a button with nothing on it, when you press it it just has a box that you can type in. And when you press enter, it normally just says 'invalid-99'

(error code 99 means wrong code) but this box is for devs (means developer its gonna be used a lot) anyway, it's for cheat codes for devs. But you might have heard that devs use a special version with cheats on for testing. But yes they do have a version, but beta testers use the codes for testing. (Because we don't trust beta tester's as much as devs) Anyway here are some codes you can use for some free stuff (only can be used once for you) There are millions of codes but we will give you some 'modified' ones ;)
