Astro Blaster is a shoot 'em up arcade game released by Sega in 1981. The player controls a ship (bearing a resemblance to the Battlestar Galactica) which can fire and move left and right. The player must continuously monitor the onscreen temperature and fuel gauges; if the ship overheats by shooting too often, its weapon is disabled, and if it is depleted of fuel, the vessel itself explodes. In Sega's 2001 Dreamcast epic Shenmue, an Astro Blaster cabinet can be seen in the YOU Arcade in Dobuita, but it has an "out of order" label on it and is not playable.
