With the 2.16 release of Bloon Tower Defense 5, Kiwi Ninja has added a new feature called "Auto Round Start". This is a very handy tool to fly through rounds (provided you have the right tower defense prepared). They released this tool along with a new beginner map called Sprint Track. With Auto Round Start enabled, I was able to complete the Sprint Track Olympian trophy (all four maps) at least 20% quicker than my quickest dedicated heads down attempts with other maps.
The Auto Round Start feature is found in the settings section of any map. The feature is disabled by default. Enable it to try it out!
The prompt received after enablng Auto Round Start:
Easy Peasy Sprint Track 🙂
Crushed this map,and you will too!
