Someone posted in one thread that if you download and play Age Of Zombies Lite, you can get a code to unlock the hoverboard in Age of Zombies (it also says this in the app description). Are there other games that do this (whether by downloading lite versions or other games by the same developers)?
If I remember correctly, an article here on TA said Apple is banning that kind of thing from going on in apps. (which I fully support)
