Defender (subtitled For All Mankind outside North America) is a shoot 'em up video game developed in October 2002 for the PlayStation 2, and Xbox, and was ported to the GameCube the following month, followed by a port to the mobile phone version published by THQ in 2003.

Featuring three-dimensional (3D) graphics, the game is set on multiple planets and moons within the Solar System where the player must defeat waves of invading aliens while protecting astronauts.

The player picks up humans, who are in danger from aliens, and brings them to a drop zone for extraction.

The enemies are a handful of other alien craft, including some ground units that can turn humans into zombies.

It contains a faithful recreation of the 1981 Defender, and an updated version with digitized sprites and new game modes.
