So I was playing the 2nd mission and I killed a bunch of covies before they jumped out of the drop pod and all of a sudden a bunch of guns started floating along the ground and shooting me, I was getting attacked by the guns and there were no enemies.
This happened to me as well. It’s really hard to hit an Elite like that when it’s just a gun strafing back and forth. There was this strange thorn bush-esque model that appeared when you kill them, too. Glad I wasn’t trying it on Legendary.
I had the same problem
Same here, thought t was quite fun to be honest trying to kill"nothing"
Sucks there is no theater support for Spartan Ops or Campaign for that matter…
I didn’t have any problems with any if the missions. But I have heard of some of the glitches on mission 5
I JUST GOT ON THE FORUMS TO POST THIS!
I was playing it, and I noticed one of the turrets was shooting at something like crazy but it wasn’t dieing. Thats when I noticed it was a needler…floating around the ground!!!
I chased it down into another room and I can say it was quite fast. Thats when I saw a close up of it. It looked like a jackal just really really really tiny.
I swear, it was weird. To bad I can’t film it 
This is a very common glitch for this mission for some reason. It not that big a deal though. I’ve found it quite hilarious to assassinate the air.
Oh, balls.
I missed this thread and made my own, but yeah this happened to me too. I thought it was hilarious.
This happens when you go in the center building all the enemies glitch under the map
first they spas out trying to get in the door then everyone goes under the map it happens to often it is yoink.
