Vorp! is the game for you
Unlike most games of this genre that are of fantasy setting, Vorp! puts you into the cockpit of 6 (more coming soon) different ships, fighting for glory. Each ships has different playing style and skill set that you can customized to fit your preferences. Like games of these type, your mission is to destroy the enemy capital ship. Further explanation can be found on the link provided below.
Also, this requires Unity3D to play, so you'll need that plug-in to play
