Do you have to update Battlefield to play Revolution?

Solution 1:

Battlefield 1 Revolution is not a new game or DLC, it was simply a bundle of sorts.

You most certainly do need to be fully up to date in order to play online (everyone needs to be on the same version after all, or things get weird). You usually cannot download updates to your PC and then plug them into you console either. Battlefield 1 does not have this, but perhaps if you contacted support they may be able to provide something? but don't expect it to succeed.

You should generally always keep your games (and add-ons, if applicable) up to date as they contain fixes, changes, and even new features.
