Defly.io is an awesome and interesting .io game with a unique twist that sets it apart from other titles. In this game, you fly a helicopter and shoot other players. You can also build towers and walls on the map to mark your territory. By marking a bigger territory and shooting other helis you can earn experience points (XP)! This game might seem like a standard io game but you can actually shoot your helicopter's weapons to destroy your enemies territory and claim it for your own!
