[UPDATE] Arrowhead has announced that, after listening to fan feedback, it decided to "revisit" the situation and make some changes for the Killzone 2 DLC for Helldivers 2.

"Firstly, we are gifting to everyone the planned second wave of the Helldivers x Killzone collaboration items today, free of charge. The distribution of those items will begin shortly, in two waves," the studio said. "As such, we're also going to extend the duration of the items currently in the Superstore from 5 days to 10 days so that you have a chance to get hold of it and reduce the risk of missing out."

Arrowhead said it is also looking into how it can bring the Killzone items back for good in the future.
