Thirty years after the events of Killzone 3, the world is a very different place, with two rival factions, the Helghast and the Vektans, living side by side divided by a vast wall. In the midst of it all stands a Shadow Marshal, an elite soldier, the best of the best. As Shadow Marshal Lucas Kellan, you’re sworn to protect your home and the values you believe in. Maintaining the fragile peace is difficult when there is no trust between either side. A series of escalating conflicts puts you on the path of a Helghast intelligence operative named Echo, who fights for the same reasons but on the opposite side. Strive to uncover the whole story as the intense, immersive combat of the Killzone series is reborn on PS4.

Apparently, it's shot up in price on PSN, which people suspect being Sony's cheap way of saying 'Look how generous we are this month!'.
Just joking its a brilliant price, and really good game once you give it a chance.
We've been waiting for it to come to PS+ for ages now, however I do think that this is the month. Not just because of the price increase but because it's not included in any of the PSN sales this month. Usually it's included in every sale, PSN currently has three sales going (games under £8, PS+ Double Discounts & Black Friday) and it's not in any of them. Guess we'll have to wait and see
