Gameplay

Fortress is an isometric scrolling shooter in which the player manoeuvres a starfighter along an alley-like terrain. The player craft burns fuel rapidly (even more when flying at altitude) and fuel tanks need to be destroyed to replenish the on-board fuel tank. If the craft runs out of fuel, it crashes. The player must avoid enemy gun turrets, rocket pits and fighters, and deal with additional problems of navigating over and through walls with force fields. The player has three lives. Completing the three stages leads to the enemy headquarters which needs to be destroyed. The game then starts over from the beginning.
