Absolutely glorious remaster of the classic Space Invaders game. Innovative, advanced, and scores of fun to be had.
When aliens living on Titan, Saturn's moon, decide to attack, they lay waste to Earth's military forces. Well most of it. You are the last remaining Tank Commander on Earth, and you are one bad mofo. Battle your way across Earth to stop the invasion, and then you take it to the skies as you hit the Titans' outpost on the Moon, and obliterate it. Next stop, the Titans' Martian colony. They wiped out all the little green men also and need to pay. After Mars, you find yourself on Saturn, and the enemy forces are strong. But not as strong as when you reach Titan itself, taking on the nest of the alien scourge to nearly end our way of life... and the poor Martians.
5 levels, 5 mothership bosses, an entire armada of Titan forces, some rogue and oddly light blue asteroids, and 1 lone tank to destroy them all. Fight your way across the Solar System as you upgrade your tank; outfitting it with extra weapons, additional bullets, faster recharge time, more powerful attacks, Shields, and deadly Smart Bombs. You start out small, but by the time you reach Titan, the force of your tank is ridiculous. But that doesn't mean it's easy. Each world you come to is upping the difficulty, more enemies, more styles of fighting, and a tougher Boss.
Not to mention fun bonus Challenge stages after every 7 waves you defeat, where harmless yet swift yellow flying saucers shoot across the sky. Destroy them all with perfect aim and you get bonus prices.
This game is complete with Highscore boards showing the scores of other players across Steam. Compare your best with others and strive to be the best. All the while this game's gloriously beautiful soundtrack playing in the background as you squash Titan scum.
The tank comander from the original Space Invaders would be jealous to see the rig you are in control of now.
