This is what the boss at Wave 80 looks like.
This run was so mentally draining. We had many close calls but we were saved so many times by my teammate's reiss stun. That move is a requirement if you wanna get past wave 70. I used a female+fritz build and i pretty much was shifted 90% of the time and found 1 mythic crate and like 2 or 3 legendaries. My teammate had 2 legendary crates, one of them being the helos buff that give you aoe m1s and the other being the fritz coordinate skill. We initially started at 3 players but one of them had to go. He was using yeager and got attack serum early on. I hope to attempt this again next weekend and try to get to wave 100 with 2 more teammates being helos and fritz respectively. I'm surprised we got this far with 1 fritz and 1 ackermann nonetheless. GGs.
