Defender 2000 is a side-scrolling shoot 'em up video game developed by Llamasoft and published by Atari Corporation for the Atari Jaguar on December 1995. Part of Atari Corp.'s 2000 series, it is a remake by Jeff Minter of Eugene Jarvis and Larry DeMar's 1981 arcade game Defender, which drew inspiration from Space Invaders and Asteroids. Defender 2000 received mixed reviews since its launch. Reviewers typically commented that the game, while reasonably fun, failed to update the original Defender to the point where its gameplay and graphics could stand out against contemporary shooters.
