FlyUFO.io is a very interesting multiplayer online game. In this weird alien world, you will have the opportunity to play as an alien and own the most advanced spacecraft in the universe. Your task is to absorb all the surrounding objects and turn them into energy. It is worth noting that you need to avoid other players' tracking and compete with them. Can you survive the confrontation with other players? The goal of the game is to absorb humans walking on the streets, cars, trees, and other objects in order to increase your power and eventually be able to take on even larger objects, like malls and apartment complexes. Click and hold the left mouse button, and then drag the cursor where you want the UFO to go.
