"THEY'RE MY FEAT POINTS AND I NEED THEM NOW!" Just kidding, but seriously, I've been through this a bunch of times before and the feat never popped, so I went through twice in a row, with no other intention, but, to get the feat, and no luck at all. Come on, Batuba, help a guy out!
Did u use any consumables or supercharges? If so on used, it’ll void the feat and you would have to retry, I would recommend highly using orbital and supply drops Feat description “Complete the Iceberg Lounge solo instance without using a consumable item or a supercharge ability”
