When the aliens first attacked, we bravely met them head-on. Soon our pilots were overwhelmed by sheer numbers. They got separated and taken down one by one. Still we kept sending the best we had. What else could we do?

Laser Sky Zero is a retro shoot'em up in 8-bit style, with endless gameplay: blast wave after wave of alien invaders in your lone spaceship, for as long as you can last. There will be powerups to help you along the way: more life, better guns, protective shields. Just watch your energy levels, and don't let yourself be cornered. Beware, some enemies can be hard to take down!
