Astra.io is a space-themed Shooter IO game that lets you control your own aircraft around the arena to shoot asteroids for a lot of points and upgrades. You shouldn't crash into those asteroids, or else your aircraft will be damaged, causing your game to come to an end easily. Attempt to survive longer, elude the enemies, or if you have good tactics, you can kill them. Be sure to upgrade the aircraft through over time to become stronger! Good luck!
