Scramble (video game)  The game was a success, selling 15,136 video game arcade cabinets in the United States within five months, by August 4, 1981, becoming Stern's second best-selling game after "Berzerk". Its prequel, the more difficult "Super Cobra", sold 12,337 cabinets in the U.S. in four months that same year, adding up to 27,473 U.S. cabinet sales for both, by October 1981. "Scramble" was not ported to any major contemporary consoles or computers, but there were releases for the "Tomy Tutor" and "Vectrex" as well as dedicated tabletop/handheld versions. Several unauthorized clones for the VIC-20 and Commodore 64 used the same name as the original. The player controls a futuristic aircraft, referred to in the game as a "Jet," and has to guide it across a scrolling terrain, battling obstacles along the way. The ship is armed with a forward-firing weapon and bombs; each weapon has its own button. The player must avoid colliding with the terrain and other enemies, while simultaneously maintaining its limited fuel supply which diminishes over time. More fuel can be acquired by destroying fuel tanks in the game. The game is divided into six sections, each with a different style of terrain and different obstacles. There is no intermission between each section; the game simply scrolls into the new terrain. Points are awarded based upon the number of seconds of being alive, and on destroying enemies and fuel tanks. In the final section, the player must destroy a "base". Once this has been accomplished, a flag denoting a completed mission is posted at the bottom right of the screen. The game then repeats by returning to the first section once more, with a slight increase in difficulty. The player is awarded an extra jet for scoring 10,000 points. A dedicated Tomytronic version of "Scramble" was released in 1982. A second electronic tabletop version of "Scramble" was released the same year in the UK by Grandstand under licence from Japanese firm Epoch Co., who sold the game in Japan under the title Astro Command. Gameplay differs from the arcade version as no scenery is rendered and the ship has no need to refuel. A handheld compact LCD version known as "Pocket Scramble" was released the following year. "Scramble" was commercially successful and critically acclaimed. In its February 1982 issue, "Computer and Video Games" magazine said it "was the first arcade game to send you on a mission and quickly earned a big following."
