Ensemble Studios have released a new cinematic for their upcoming Xbox 360 RTS, Halo Wars. Entitled "Five Long Years Part 2," this cinematic can be viewed below, here, or via the Xbox LIVE Marketplace.
It's an excellent piece that's both beautifully animated and introduces us to some great characters, including this time period's Arbiter. A completely different character than that featured in the Halo trilogy, this Arbiter seems to be a rather nasty one.
The UNSC Field Manual has also been updated to reveal the UNSC Cobra, an new anti-armour vehicle. It also doubles as an anti-building vehicle that needs to root itself in place. Looks like a complete rip of the Arclite Siege Tank from Starcraft, but on wheels instead of treads.
