With plans for a big-budget Halo movie still trapped in development hell, it appears that fans will have to make do with this re-edited web series for the time being. What they'll make of the decision to sideline Master Chief until the final act is another thing – but the good news is that once he and the Covenant finally turn up …Forward Unto Dawn delivers on the promise of its source material. As well as a strong AVC 2.40:1 1080p encode and dynamic DTS-HD MA 5.1 mix, this disc also delivers plenty of extras, including 10 behind-the-scenes featurettes.
