They arrived one day. They attacked the outpost. Funny little green guys shooting purple energy zigzags. All would have been lost were it not for the lone defender in his little ship. He fought them.

Scott's Space Invaders is like the good ol' space invaders that you remember, but with a few additional perks and powerups, some new tricks, and designed to operate on modern PC hardware. It requires windows XP and DirectX 9.0 or higher.
