After failing to do the Easter Egg once, I decided to invite players from a LFG posts on console. Found 3 people willing to do the Easter Egg with me.
After about an hour, we had finished it with relative ease. The boss fight was finished in 3 cycles due to 2 of us having an RPG.
So… Get to the cut scene. 1 dude had already disconnected before the Boss Fight, another dashboarded right as we finished boss fight as he had already done it. So it was me and one dude left. During the cut scene, he dashboards. I didn't know at the time… On private matches the Host never migrates. Game ends, I don't get the achievement, I don't get the gateworm. I'm so destroyed.
But I'm so grateful, I kicked the guy who dashboarded out of rage, and the last dude in the party offered to do it again with us 2. We unfortunately had to build all bows and I was left on 200-300 ping (2 bars), but we pulled through and got the boss fight done quickly. For some reason the Boss Fight wasn't laggy at all. I'm just so happy that I got it done lmao.
