From HD2 Discord
Attention, Helldivers
We are beginning the distribution of the Ingress-81 cape to recognize those who bravely worked together many long hours to bring Station-81 back online in May.
As always, please allow some time for the item to appear in your game.
This was the first HD2 ARG. It will be probably be the last for quite some time. When the ARG ended, there were no plans to host another one.
Well, damn. Thanks for letting me know
