Pulstar is a 2D side-scrolling shooter where you control your star fighter as it navigates through stages filled with enemies trying to destroy it. The game allows you to upgrade your main weapons by collecting power-ups, and charging up energy enables the release of charged attacks, which consume power-ups. Your ship also comes with an "option" gun pod that floats around it, offering several configurations for protection or increased firepower.
The gameplay involves navigating through levels while avoiding enemy fire, and destroying as many enemies as possible to progress. The game features pre-rendered 3D sprites and fully animated cutscenes between each level, adding a touch of depth to the 2D gameplay.
