BTD Battles is a multiplayer, real time, competetive version of the Bloons Tower Defense series by Ninja Kiwi, with different strategies, tracks and awards. During a 1v1 match, as rounds progress, stronger and stronger bloons get unlocked, meaning that you will have to improve your defenses. At the same time, players can send stronger and stronger bloons to their opponent to get past their monkeys, and the last player to run out of lives wins the match.
