PS3 players of CCP Games upcoming EVE Online MMOFPS tie-in DUST 514 will be required to pay an initial "cover charge" for the game when the game launches, though the charge will be refunded with in-game currency.

In an interview with GamesIndustry.biz, CCP Games CEO Hilmar Pétursson notes that players will basically get the game free of charge, but will be required to pre-buy $10-20 worth of credits at launch, though he also leaves the door open for the possibility of the game going "fully free-to-play" down the line.
