3D Starstrike is a wireframe 3D shoot'em up heavily inspired by the first Star Wars movies. Each level has 3 phases: first a space battle with enemy fighters, then a ground attack sequence against defense bunkers and towers, and finally the "equatorial duct run" sequence, where the player must dodge catwalks and flak while flying along the duct. At the end of the duct is the power station that must be destroyed. Once destroyed, the player proceeds to the next level.
Each hit reduces the player's spacecraft's shields, and the laser guns need time to cool down so the player can't fire at everything.
