Defly.io is a great addition to the world of IO games. Similar in a way to slither and paper type of games where you have to fight for territories, this game puts the player in the shoes of a helicopter pilot. The goal is to build walls on the fly (pun intended) and capture as much of the map as possible while avoiding collisions with the structures that other players have built.
You have to be careful, since the enemies will try to lock you in, and the only way to get out is to destroy their structures with bullets, which can take a while. Enemy fire can also harm the player directly and vice versa.
If you want to experience a new twist on classic IO games, play Defly.io!
