A new Halo 3 update from Bungie splurged onto its website features a heaping helping of information on the sequel's M12 Warthog vehicle.
"The M12", the developer says in its description of the vehicle, "is primarily used in a scouting capacity, or as an integral part of a mechanized infantry unit. In the case of the LRV and LAAV variants it can hold three soldiers including the gunner.
"The mounted weapon includes a battery for short term operation separated from the vehicle, but normally operates on the vehicle's power supply. The vehicle is powered by a 12 liter hydrogen-injected ICE and can reach speeds up to 125 kph (78 mph)."
M12 Warthog weapon statistics, field use and observations of soldiers about the vehicle are additionally included in the update, along with one of those QuickTime 3D screenshots thingies.
