for anyone who plays no return mode in the last of us 2 remastered

so this is for those, witch I think is verry few, but for those who have played no return mode in the last of us 2. I need help with the theater infestation boss, I've basically tried everything but still am having trouble, for those that want to try and help via shareplay. please tell me your PSN tag if you know it, you can find me as awesome guy_316, exactly how it's typed out. thanks.

I have had trouble with that boss for months!
I used to back up my save to the cloud just before fighting him, but I recently lost PSN+, so can no longer do that.
That is the best I can suggest, because then, you can try different stratigies with the same geer.

It just occured to me while writing that that was posted months ago.
Shows how little progress I've made, since it is November, and I still haven't beaten him.
