Surround is a video game programmed by Alan Miller and published by Atari, Inc. for the Atari Video Computer System (later known as the Atari 2600). It was one of the nine Atari VCS launch titles released in September 1977. Surround is an unofficial port of the arcade game Blockade, released the previous year by Gremlin. As such, it is the first home console version of the game that would become widely known across many platforms as Snake. As with other early Atari games, it was licensed to Sears, which released it under the name Chase.
