Defly.io - a game to capture the territory. You need to control the helicopter, put points on the map and connect them with lines to capture the territory. Take possession of the whole map and become the most powerful on the server.
If you see foreign territory, shoot at the fence and grab this part of the map, but be careful: the owner may notice and destroy you. Do not forget to check your possessions, because other players may attack them!
With each capture of a new part of the map, your level rises. For each new level points are given which can be spent on improving your helicopter and strengthening fences. The more territory you have, the higher your rating.
