Yesterday we announced that free-to-play MMO shooter Warframe was coming to the PlayStation 4 this Fall. Now we’ve got the first gameplay trailer showing off the game running on the PlayStation 4. Developer Digital Extremes describes Warframe as “Mass Effect meets Ninja Gaiden”. Judging by the PlayStation 4 gameplay trailer, we see a bit of Metal Gear Rising Revengeance in there as well. Warframe will be a PlayStation 4 launch title, and will also be available on the PC.
