Defender

Released in conjunction with a 3D update of the classic arcade game on consoles, the Game Boy Advance version is also an update of the original but retains its side-scrolling gameplay. The cartridge includes several variants of the game. The player's spaceship flies left or right over a scrolling landscape that wraps around after a few screens. The goal is to destroy all invading aliens before they can capture the humans. (mobygames.com)
