Stargunner: a cool mid 90's style, retro arcade game.

Similar to Galaga/Lost Viking, or something I think was called Defender on Sega, it's a scrolling space shooter with some ship customization. I like it. Apparently there were two games by this name, one from 1982 and another from 1996, so this would probably be the 1996 one if not a remake. Found it on GOG, and it's free and neato.
