Today, IGN can confirm that Warframe, the “space ninja” co-op game, is coming to PlayStation 4. It will launch alongside Sony’s new hardware, and will follow a similar free-to-play, microtransaction model as the game does on PC. (We gave the game's beta a 7.0 on PC, in case you’re curious.)

I checked it out on
youtube and for a F2P game it seems to be very high quality with a SP and Online COOP mode which you don't get with some F2P games. This game looks to be very fun, especially when playing with friends, will definitely be checking this out on the PS4 this fall.
