A NOOB's Review of Call of Duty: Black Ops Cold War (Xbox Series X)

Call of Duty: Black Ops Cold War is now out and I got a copy on the Xbox Series X to check out. I never really sat down to play a Call of Duty game before so this was my first time really getting impressions of it. What did I think of Call of Duty: Black Ops Cold War? Do I think it's a buy?
