CHAMP Invaders

Get ready to stop the invasion with CHAMP Invaders, the seventh release from CHAMProgramming. This game offers three modes of play: Classic, which is like an arcade version; CHAMP, which has enhanced graphics, sounds, and power-ups; and Deluxe Classic, which is like Classic with the addition of intermissions, splitting and dropping invaders, and much more.

CHAMP Invaders has three skill modes for one or two players. You can choose from a joystick, mouse, or keyboard for your controller, as well as the special CHAMP Cable(tm) (sold separately) with an old ATARI (R) digital joystick.

We hope you enjoy the results.
