Yesterday I updated the Horizon Zero Dawn: The Frozen Wilds post with the information that the DLC was available for pre-order on the US PlayStation store, but sadly not on the UK/Europe store.
I also tweeted @Guerrilla Games and @PlayStationUK to ask when The Frozen Wilds would appear on the UK/European store and if we would get the same PS Plus members discount. I received this reply;
Apperently the PlayStationStore in UK needs some more time to push the DLC live. EU will also have a PS Plus discount.

I actually thought it was really nice of Guerrilla Games to reply and quickly as well.
Turns out it did not take too long for PlayStation to push the DLC live. I have just checked the UK store and I am very pleased to say that The Frozen Wilds is now available for pre-order.

As you can see from the screen shot, the game will release on 31st December, the same time as the US and we get the PS Plus discount, bringing the DLC down to £14.39 from £15.99
Even at £15.99, The Frozen Wilds is a very good value for money DLC, apparently there will be about 10 hours worth of gameplay, that’s probably not even counting exploration and any new trophies. That equates to £1.59.9p per hour of gameplay, possibly even less. You can’t get much for £1.59 these days.
Only 199 days and counting until we get to go on our next Adventure with Aloy.
