My friend got to level 94 without cheating on BTD4!!!!! I'm not kidding! I swear to god i'm not lying!!!!!!!!!! He did it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I don't call that very exciting. How about you trying to do it instead of your friend? Your challenge?
Sorry Firetail, I don't know. But I do know some strategies that I can share, like what this whole forum is supposed to be about!
Anyway, Strategies. It was posted before, but some people might not have seen it, so here is a good way to go.
Always use the least possible amount of defense. Make sure that you don't have anything unnecessary. Save all the spare money to buy and build Banana Farms. Eventually, they'll be BRF's and you should have at least 4. By this time, you'll have a lot of money and you can get a lot more defense. In the previous post about this it said that you should be able to get a Banana Farm at Round 16. Instead, try to get one earlier on, like 10. I got mine at 11. As always, test things out on Sandbox, like a un-upgraded boomerang against 20 reds and go from there, with 20 blues, greens, etc. Hope this helps!!
