Blockade

Blockade is an arcade video game developed by Lane Hauck and Ago Kiss for Gremlin and released in November 1976. It is a two-player game where each player controls the direction of an arrow on the screen which creates a trail behind it. The object is to avoid any walls surrounding the playfield or trails created by each player for a select amount of turns. Blockade spawned many clones which came to be known as snake games.
