Microsoft has tonight released this teaser trailer for Forward Unto Dawn, its series of live-action shorts set in the Halo 4 universe.

Not that there's much live action here, but then, that's why they call it a teaser trailer.

In May, we brought you some set pics from Simon Fraser University in Vancouver, Canada, where much of the shorts have been filmed.

Apparently a proper trailer will be released later in the week during Comic-Con.
