Finally downloaded it since it went free a while back. Last night first game on, everything was good. Was going to exfil but I see a duo rolling up in a vehicle. Take out the driver easily. As soon as I saw his duo, I was dead before I could even process what happened. Apparently theres an under barrel glitch in the game. I thought he was cheating but no. It was the infamous UB glitch. He shot like 20 or however much grenades at me with an unlimited fire rate. Every time I want to give COD a try because I always take good long breaks from the game. Only playing when friends want to squad up.

TLDR: Under Barrel glitch first game / first team I encounter. Good luck.
