Star Voyager

Star Voyager is an action game similar to Star Raiders. You control the space ship Star Voyager from a first person perspective; your objective is to make your way through seven star portals to save the Capital Starport, destroying enemy ships along the way. On each level there will be multiple enemies to destroy. Using the Star Voyagers weapons (either lasers or photon torpedoes) you need to destroy the enemies before they destroy you. (mobygames.com)
