Williams' 1980 arcade Defender used five buttons and a joystick and was famously difficult, so Atari's 1981 Atari 2600 conversion had to rethink almost everything. Your ship still patrols a scrolling planet surface, shooting landers before they carry off humanoids and turn into mutants, with a scanner at the top of the screen showing where the action is.
With one fire button available, the extra functions moved to places on the screen: diving below the city skyline and firing triggers a smart bomb, while flying up past the top of the play area and firing sends the ship into hyperspace. To save processing power, the ship blinks out of view whenever it fires, which critics mocked at the time. Flicker is heavy, but the game sold in large numbers and keeps the arcade's core loop of rescue and destruction.
Tips for Defender
Use the scanner to spot landers grabbing humanoids and get there before they reach the top.
Because the ship vanishes while firing, it cannot be hit at that moment, which helps in tight spots.
Save smart bombs for crowded screens where several enemies are close together.
