share experience about the game Castle Defense HD Recently Im working on the game <Castle Defense HD>, and here is some advice and skills playing this game summaried by myself below (hope its helpful): In Adventure Mode you wont get much breads as in PvZ, so you should take good use of magic (e.g. lighting) to protect cookers. Its not easy to pass every level for only one time. Personally I dont recommend go IAP. To understand every role in this game is the key to clear all the levels with high scores. For the racket soldier, maybe theres not enough archers to fight against them at the beginning. You can put a cooker (or something cheap) in front of racket soldier so they exploded together. Cooperation between Shield Soldier and Hidden Weapon Put a Shield Soldier (or Shock Wave) to accrue enemies, then kill them with Hidden Weapon or A-dou.
