HACKED version is a version of the game where the rarity of pokemon is way more common and your pokemon gain way more exp.(I beat a ratata and bulbasuar gained 200,000 exp. and evolved!) Unfortunataly, you cannot recive the mystery gift in hacked version.
Shadow & shiney pokemon are also in PTD. Every once in a while you will run into one. If you attack them, they instantly faint but you can cach them without damaging them. Shadow pokemon automaticaly know shadow blitz and shadow wave. Another veryation of the game is PTD2:Jhoto's Shadow. I dont know anything about the game but it sounds fun and you should try it for yourself. Keep in mind you must have an EMail acount to play PTD. The account created is valid for all the Pokemon tower defence games. If you are stuck on a level, ask me at SnoGolemsRoc@gmail.com.
