CCP said Dust 514
is free to play, but for now you're going to have to give them
some money to get into the game. The price isn't finalized but you're looking at $10-$20 to get your groove on in the MMO FPS.
Dust 514's going to be relying on microtransactions to garner some income, but for the initial run you'll get the amount you put in back as in game credits. CCP is stating that this charge is used to help with the initial launch and maybe down the road, they'll go completely free to play.
If you were going to buy some stuff in the game anyways, not that much of a deal but for those looking for a completely free experience, you might have to wait a bit.
Considering that new games cost in the $50-$60 range, the $10-$20 doesn't seem that bad of a charge and you do get that money to pick up some items to help you out. Still, don't say that it's free to play when you need to put down some cash to get in.
