Best shooter on GeForce Now

Hi everyone. Just wondering what you think is the best shooter on GeForce Now. It's so frustrating playing COD.....even DMZ its impossible to do missions. Id love a COD style shooter with missions and bots for enemies. I don't play enuf to be able to keep up with all the really good players but just wanna be able to jump in, play for and hour or two and come back to it the following day.
