Free For All

No rules, no teams, just a lot of ships destroying each other. Fifty players maximum. The game restarts every six hours.

Controls

Powerups

Upgrades

Destroy asteroids or other ships to collect gold. Spend gold to upgrade your ship or, in Satellites mode, the satellites your team controls.

How to capture satellites

Fly into a satellite's circular capture area and stay inside it. The contest bar above the satellite fills toward your team colour as long as no enemy ship is contesting the same area, and the satellite flips to your team when the bar is full. An enemy inside the area stalls the capture, so clear defenders first. Once a satellite is yours it shoots at enemy ships, and gold can be spent to upgrade its guns.
