They really should just give an extension to the current battle pass. I don't think they really care that much about it 'not being the time' to release a new season. It's just a convenient way to buy an extra week while trying to develop Season 5 in coronaworld, or maybe even just polish up Season 4.
I finished the pass forever ago, the thing I kinda killed myself on was grabbing the bunker blueprint solo (in 4-man Plunder) on the assumption that it might go away or be replaced by some other easter egg thing for the next season. First try took forever but I got the correct code, but the bunker had been long open by the time I got there. And some shit had gone down. Someone had set up a shield turret in there. Kinda sorry I missed it. But it took a while alt+tabbing to guides and finding phones despite knowing the general locations.
After that I did a few other attempts, sometimes getting really bad initial phone luck, other times just mishearing the numbers Sovietsky. Finally got another correct code, went to the bunker, and wouldn't ya know it, there were two full teams camping it. First attempt I killed a guy at the fire station tower but got flanked by his teammate, second try I landed on the hill to the left of the bunker entrance, won a 1v3 with just the 2 plates on my chest(some real shitters in the Plunder lobbies, lmao) and got the door open and the blueprint right before the match ended.
Yo am I crazy or does the Mud Dauber you pick up have a shitty sight on it, but then the actual blueprint is a pretty solid no sight hipfire build?
I might have to run it untweaked just because it's so close to some of my previous MP7 builds. But I also got that Grau/MP7 purple tracer troll pack, and the troll tracers are kind of hard to put down.
