With less than a week to go before Assault Heroes 2 arrives on Xbox Live Arcade (it's scheduled to drop on May 14), Sierra is ramping up the publicity, releasing a new two part trailer featuring some of the game's massive bosses. There seems to be an obsession with throwing mechanized versions of various fauna at players this time around, as the bosses featured in the video are the Mecha Gorilla, Mech Scorpion, Mecha Killer Orca (really?), Mecha Snake, Mecha Quadruped, and Mecha Demolition (guess they ran out of animals with that last one). Suffice it to say that the bosses are appropriately huge and they seem to be capable of dealing death quite adequately. We approve. Find the second trailer after the break.
