Protector

Protector is a two-dimensional side-scrolling shooter game much in the style of Defender set on the surface of Haven-7, where the player controls the Starblade ship as it navigates left or right over the terrain, where the main objective is to destroy alien invaders, while also protecting the inhabitants on the planetoid's landscape from being abducted by the aliens. There are a total of 15 stages, with the progress being kept after completing five stages via the cartridge's EEPROM but high-scores and other settings are not saved. There are also three difficulty levels, however, the game's special edition has a set difficulty and finishing the game unlocks an expert difficulty that can be activated by holding Option on the controller before starting a level. It also features support for the ProController.
