For a concept so obviously badass it's a wonder it doesn't get used more. Besides Warframe, we have Metal Gear, the faggot from Mass Effect 3, the faggot from Overwatch who's clearly a Gray Fox ripoff, and maybe some toku heroes who aren't primarily vidya anyway. Seems like there's a vast, untapped market here. Mostly we just need a game like Metal Gear Rising but with more weapons and weapon customization, more of an open world design (but confined enough to where it's not just a vast stretch of nothing), and maybe some vehicles.
