Dan Bird, Spartan Vanguard and “Official Demo Guy” (for want of a better title!), has filmed a short video that demonstrates a few activations in Halo Ground Command during a normal game turn. It was shot at Board in the City in Southampton using Dan’s advance copy of the Battle for Reach boxed set.
The video demonstrates the reaction mechanism, as well as supply drops, and basic movement and shooting. Of course this is just one small example of what gameplay is like in HGC, but it’s nice to see the game in action.
