After receiving a Playstation 4 last year, I completed the Killzone: Shadowfall campaign on the hardest difficulty. At some points it was very aggravating and I almost "Rage Quit" the whole thing. But, overall the game was very enjoyable and I highly recommend playing this game as soon as possible. The multiplayer is very enjoyable and can be slightly addictive. I also have been playing Killzone since the second game release, and have been a fan of the series since.
