Had a go with the gun and can genuinely say, that this is how all fps's should be played in the future. Sony and the game devs have got this spot on. It's accurate, fast and of course, really immersive.
Certainly takes a while to get used to it, but no different to when fps's first started using twin sticks and introducing more and more buttons.
Anyone got any questions?
Sure! My main concern is moving and panning the camera. It's really a natural thing that comes with time or can be a throw-back handicap?
