Believe it or not, Halo 5 is already pretty far along in its development. This footage from some kind of internal multiplayer test, created and uploaded by Youtuber devinsupertramp, shows the next game from 343 Industries in action, and it's totally not fake. No way, people.
I do find it a bit strange that old school and forgotten Halo weapons like the SMG and flamethrower are back. And it's definitely weird that the HUD looks more like Halo: Reach's than the one in Halo 4.
But with graphics this life-like, how could this be anything other than real footage of Halo 5 running on the next Xbox system? Let's just hope they fix those server issues before the game is released—Halo 5's pacing looks slow enough as it is. It's almost like those are just people walking around in costumes.
