Strategy X is an arcade-style action game released for the Atari 2600. In this military-themed title, players control a tank navigating through a vertically scrolling battlefield. The genre of Strategy X can be described as a shoot 'em up, with the objective being to dodge obstacles, outmaneuver enemy tanks and turrets, while traversing through a maze-like environment to reach an enemy fortress at the end of each level. Strategy elements come into play as the player must manage limited ammunition and fuel while deciding the best route to avoid or engage foes and obstacles.
