Help your ship escape the gravitational field obstacle course. Learn to use the tractor beam to carry orbs along with you, so you can move them to their goals to unlock the exit portal and fly out of each level. Watch out for blocks and other obstacles. Don’t hit the floor or you will burn up. Beware of the auto-aiming gun turrets. You can shoot back at the guns and obstacles you wish to to remove. To unlock the next level, complete the tasks and get your rocket to the portal without incurring too much damage. Follow the in-game instructions and have a great time playing Gravity Thruster!
