Star Citizen Gameplay Trailer

A new trailer from Star Citizen shows off gameplay from the alpha version of Cloud Imperium's upcoming space game (thanks Videosift via Ant). The description has a bit more on what we're seeing here:
Our universe keeps getting bigger with the release of Star Citizen's Alpha 2.6 patch featuring more ships, more content, and more to explore. Plus, two new ways to play - Pirate Swarm where pilots can dogfight against villainous outlaws, and the all new Star Marine, our intense head-to-head FPS mode.
