Idk... I don't think too many iPhone games have cheats (which is unfortunate). At the most, they have a Survival Mode unlocked after beating the game but that's it.
I've got master on all of the easy levels, and some of the normal, and haven't unlocked any cheats. Unless it dosen't tell you.
Maybe they mean level up rewards. so far I'm 20 something and have bullet deflection and a extra life thing. any cool later ones?
There are 3 cheats/easter eggs in the game that you unlock by getting Master rank on normal and hard mode missions. They're unlocked for every 5 masters you get total, so at 5, 10, and 15. It'll notify you when you get one and they show up in the options menu. They are as follows... 1. Crazy Speed Mode (makes the game run at 180% speed) 2. Unstoppable Mode (damage no longer juggles you around or interrupts your attacks) 3. Infinite Ki (your super attack is usable at all times) Turning on any of these makes new records in the campaign and survival mode not get recorded btw.
