Ultra Massive is the only hero with his own gravitational pull and the Earth's only hope against invading saucers! Use this powerful hippo and his friends, Miss Massive and Mini Massive to intercept the invader projectiles. As predicted by Einstein's Relativity equations, and the laws of gravitational attraction, Ultra Massive's gravity pulls the projectiles into centrifugal (or centripetal) orbits, then releases them back towards the invaders on devastating return trajectories.
No algebra, physics, or calculus is required for this tremendous feat, only fast fingers and quick thinking are necessary to perform this orbital ballet, defeat all the invaders, save Einstein, and become the most massive hero in the galaxy!
