Sabotage is a top-down shoot'em up with puzzle elements. The player controls a spacecraft and must fight wave after wave of enemy ships to reach the end of the level. Between each level is a puzzle sequence in which the player must navigate a top-down maze and pickup a piece of blueprint while dodging enemy drones falling down from the top of the screen. Once the maze sequence is completed, the player is given a code for the next level. At the end of the final level, the player has collected enough blueprint pieces to find the weakness in the enemy's mothership and destroy it once and for all.
