Atari Invaders is a graphical hack of the game (it plays exactly the same as the original 2600 version), having changed game sprites, as the invaders, players' laser cannons, and the Command Alien Ship look different, as they were all changed into various Atari 2600 persona, as the player's laser base was changed to the player's ship from the 2600 game Asteroids, the bunkers is the Atari "fuji" symbol (plus players can shoot through the gaps in them), the row 1 invaders are robots from Berzerk, the row 2 invaders is Pac-Man, row 3 invaders is a player from Football, row 6 is a ghost from Pac-Man and the Command Alien Ship is a plane from Combat.
