This challenge was suggested by robogamer5399 in a KZfaq comment. In it I have to get to round 20 on all adventure maps on hard mode without using turrets. I will however still be using yard turrets from rescued red ants as those can easily be used accidently and don’t have much impact anyway. I will also be using my old save for convenience.
I decided to play for longer than I would normally do as it looked like I was close to losing. And that ended up being the case later. 29 is quite a good round for this challenge so even though this is an easy map it doesn’t seem like I will struggle that much on future maps.
