Developed using Unreal Engine 3, Hawken looks fantastic, putting players in the cockpits of lethal mechs, each with their own weapons, loadouts, and perks. Through kills and match victories, players will rank up and unlock new items for their mechs, opening up new tactical opportunities and new play styles. Being a free-to-play title, players also have the option of speeding progress along through the use of real money transactions, though these do not grant additional power or a competitive edge over players who progress through exclusively through the use of experience.
