Obsidian Entertainment celebrates E3 with a new "roles" trailer from Armored Warfare, detailing a new role system and the types of tanks players will command the upcoming free-to-play military tactics game. Here's a summary: "The roles of the Main Battle Tank (MBT), Recon and Artillery units in Armored Warfare will offer players an endless amount of strategies in taking on the competition in a given match. Players must weigh the cost-benefit of each role in every scenario. MBTs are bruisers that can dish out damage and take it, Recon tanks sweep swiftly throughout levels to help flank enemies and spot them for artillery strikes, while Artillery units rain destruction on enemies from a distance."
