The new SMG in Season 2 can be unlocked a few different ways.
Season 2 of Call of Duty: Black Ops 7 and Warzone has arrived, and there's certainly some buzz thanks to the sheer volume of content we're receiving. Treyarch isn't holding anything back, as Season 2 has delivered over half a dozen multiplayer maps, several game modes, and some highly intriguing weapons. One of those weapons is the REV-46, a new SMG that you can unlock using a couple of different methods.
We'll show you how to unlock the REV-46 using all of these methods in Black Ops 7 below.
Unlock the REV-46 in Black Ops 7 Season 2
Since the REV-46 has arrived at the start of Season 2 in Black Ops 7, it's a Battle Pass weapon. This means the primary way to unlock the SMG is by progressing through the Season 2 Battle Pass and unlocking new tiers.
The REV-46 is available to unlock as the "HVT" on Battle Pass Page 3. Being the "HVT," you have to unlock every tier on Page 3 using Battle Pass Tokens before you can unlock the weapon, which also requires a single token.

In addition to being available on Battle Pass Page 3, the REV-46 also has a regular and a BlackCell blueprint available on Page 11. Obviously, you'll unlock the base weapon first on Page 3, but the blueprints on Page 11 are even more of an incentive to grind out the Battle Pass.
If you want to go a route other than the Battle Pass, there will be a store bundle coming out that contains a weapon blueprint for the REV-46. There is one bundle currently available to buy with a REV-46 blueprint, and it costs 2,400 COD Points.
And that covers everything you need to know about unlocking the REV-46 in Black Ops 7 and Warzone.
