@DontDoItInPublic: To unlock it, i think you have to buy it with kreds :/ or you have to beat the game on all the campaigns. Those are the only ways I see how to unlock the dragons...
Hey yoda1245? Ya know you can take off the caps? And they have made the pause button, go to ninja kiwi, and look at bloons tower defence games, they already made a BTD5 :/ and it has the pause button >:/
For all the people crying about the prices getting higher, they didn't, they just took out all the "special price" reductions, and what you guys consider prices being raised is actually the original price of the gun. Play the game and quit blabbing! :D
