Thankfully for me, FPS has become something of the summer blockbuster of gaming genres. They're the easiest to make the translation from "big budget movie" to "big budget game with movie-like sequences in first person". As such, the games have gone from being a way to show off technical prowess in gaming (remember that Doom was a 2D world made to look 3D, which is why it was particularly awesome) to single and multiplayer experiences with huge cinematic potential. They've also become what once the sole domain of the mouse and keyboard set to hugely popular on consoles.
For PlayStation 4 launch titles - FPS fans get Call of Duty: Ghosts, Killzone: Shadow Fall and Battlefield 4: Battlefield 4 has no subtitle. As was inevitable, I've had a chance to put all three through their paces and these are my thoughts on them.
