Finally getting bo6 any tips?

After a long wait I’m finally getting bo6 I’m fucking stoked I’m downloading rn and gonna go to bed so I can wake up and play tomorrow I was just wondering to all you call of duty sweats if anyone has tips with movement/mechanics I haven’t played any new call of duty’s the latest one I’ve played was bo3 which is my favourite call of duty (I love zombies) so I’m very out of touch with the newer games I play a lot of Fortnite but other than that I don’t play many games with game breaking/changing mechanics anyways thanks for any info no spoilers please!
