YouTube’s member ‘FPSGeneral’ has captured some new footage from Sony Online Entertainment’s upcoming Planetside 2. This is brand new, in-game footage straight from GDC 2012, so be sure to give it a go. And let us tell that it looks great. Planetside 2 comes with a new game engine and will be powered by Nvidia’s PhysX technology. PlanetSide 2 takes all the groundbreaking features from the original game – massive multiplayer battles, distinct empires to rally around, and enormous continents where intense ground and air combat unfolds – and adds features that modern gamers have come to expect out of the FPS and MMO genres. The game does not have any ETA as of yet. Enjoy!
