Gearheads of War

All I can say is wow.  Shows boss enemies, including the executioner, a giant scorpion, and some new humanoid leech, like from Resident Evil 0.  A new bat enemy is also shown.  Environments range from the village, to a savanna where you take part in a chase sequence where villagers attack from trucks and motorbikes.

Anyways, its available for download at Xbox Live Marketplace.
