An entertaining shoot em up on the Atari 2600 – still actually plays a good game
Beamrider takes place above Earth's atmosphere, where a large alien shield called the Restrictor Shield surrounds the Earth. The player's objective is to clear the Shield's 99 sectors of alien craft while piloting the Beamrider ship. The Beamrider is equipped with a short-range laser lariat and a limited supply of torpedoes. The player is given three at the start of each sector.
To clear a sector, fifteen enemy ships must be destroyed. A “Sentinel ship” will then appear, which can be destroyed using a torpedo for bonus points. Some enemy ships can only be destroyed with torpedoes, and some must simply be dodged. Occasionally during a sector, “Yellow Rejuvenators” (extra lives) appear. They can be picked up for an extra ship, but if they are shot they will transform into ship-damaging debris.
