Exo Survival Bug?

Unfortunately, I just found out this is not a one time bug. Playing again a few times and experienced the same effects. It actually got worse than before. This time, as players went down the game would lag worse. By the time 1 person was left standing the
framerate dropped severely and was almost unplayable.

We were also having enemy spawn issues again. Around 6 rounds before they stopped spawning completely, they were only spawning 2 at a time. That on top of the lag was horrendous.

Also, 2 of our players lost control over scorestreaks. They were not able to activate them.

Same exact thing happened to my friends & i TWICE over new years break, it's super annoying because like you said we had to down ourselves but we were on a roll and would've survived for a while longer. I was trying to find something about it on the internet
but your post is the only one I found

Same exact thing happened to me & my friends twice this past weekend, both times we were in the 2nd or 3rd map flip & in a "Defend" game. As the levels went on, less & less enemies were spawning & everything was slowing down until eventually they completely
stopped coming & we were forced to down ourselves and start over. Beyond annoying because there's no use in playing when you wind up having to just randomly quit.

Interesting, nothing like that on my end. perhaps it was just one of those "one in a million" kind of bugs.

Oh & both times it was during a "Defend" mission
