You'll need to check the store every day to make sure to get the free DLC!
[UPDATE] After reading the PS Store update post on the PS.blog, it appears we won’t see the Perseids DLC today. Don’t get your hope down, we are still getting this DLC, eventually! Killzone 3 DLC for Europe still releasing tomorrow when the store updates.
Killzone 3 DLC was planned to release in North America on the 19th but was released early as a treat. So that leaves the Killzone 3 pack to be release in Europe on the 20th, Wednesday. But, there is a possibility we may see new seasonal DLC today 19th, Tuesaday in NA and on Wednesday for Europe.
So, what is this DLC? Perseids Meteor Shower (?)which the costume pieces are: “base”, “ends”, “tail”, “helmet”. Kind of excited to see what the actual pieces will be. There is a chance this will release in NA today (and Europe tomorrow) because the Meteor shower is from July 17 – August 24. Today is the first day the PS Store will update in that time frame. This is just a guess assuming they release the DLC within the time frame of the meteor shower.
Also, keep in mind, there is another season DLC, International Peace Day (?) which is on the 21st of September. This costume includes: “globe”, “ends”. So I’m guessing a head piece that is the Earth?
