Looks like it is still using UE3. I think this is different from In Country, which was going to UE4 and to become standalone. As it was sparsely updated I think it may be dead. That is too bad, because no doubt this will be like Rising Storm and RO2 with different weapons. Meaning lots of grinding, loss of unlocks when quitting before the hour long match concludes, the horrible suppression system, and constant nauseating black & white screens with washed out wooing sounds every time someone dies, a grenade goes off, or someone farts on the other end of the map.
Maybe a Steam sale at deep discount will make me get it. Or maybe they will go back to RO1's roots and dump the fluff, but I highly doubt that. KF was a success due to its mainstream grind nature and multitude of immersion breaking, out of place skins to collect. That clearly influenced TWI when making RO2.
