Earth Attack

Earth Attack is a Canadian-released copy of Atari's arcade title Defender. Players cruise through the sky shooting enemy UFOs and rescuing the humanoids that the aliens are trying to abduct. In addition to "smart bombs" which decimate all enemies on screen, the player's spacecraft controls also include a "hyperspace" option (immediate teleportation to a random area of the playfield) inspired by the similarly-named feature from the arcade classic Asteroids.
