I feel like the back story for Hawken is very fuzzy. If the new devs came up with a single-player or even co-op campaign that was offered as DLC, I think it would generate some interest. Therefore, the online play would be still be FTP but the actual campaign would be available to those who decide they want to pay for it.
Hell, maybe even add extra unlock-able cosmetics only to those who complete the campaign or unlock achievements. It could also be used as a way to unlock weapons and items faster than just playing online.
