First Time Halo Player

I last played Halo on the PC in 2002. Got fed up of the COD series and got Guardians coming today in the post for my Xbox One. Any tips on where to start!? Dive into multiplayer or get into a single player campaign?

I always start with campaign.

But on the multiplayer side, start with Warzone until you get the hang of it. The arena in this game is super competitive. It’s the best part.
