Furthermore, Ranked Play in Warzone 2.0 uses a similar ranking system to that in Call of Duty: Modern Warfare II multiplayer (learn more about it here). There are seven standard Skill Divisions, with all players beginning at Bronze I at the start of Season 03 Reloaded.

Everything you have earned on MW2 Multiplayer will be reset. This will not affect your Campaign / Spec Ops progress. Note - There is no easy way to revert your rank to what it was before it was hacked. You can either stick with your modded rank, or reset it.
