A new secondary weapon has made its way to Call of Duty: Black Ops Cold War and Warzone. The AMP63–which was previously leaked–is now available to unlock in traditional multiplayer or in Warzone matches. A previous, yet brief, glitch was making the AMP63 available to some players as the challenge to unlock the weapon was showing up in both Warzone and Black Ops Cold War.
The AMP63 can be unlocked by using a pistol to get five kills in 20 different matches. This is rather easy challenge to complete, and can be done in either Black Ops Cold War or Warzone, but will likely be easiest in regular multiplayer.

If you don’t want to complete the challenge, the Gamma Ray DLC bundle can be purchased through the store. This bundle is priced at 1,000 COD points ($10), and it comes with a weapon blueprint, three small cosmetics, and two tier skips for the battle pass.
It’s weapon output is described as having “high amounts of damage in a short period of time thanks to its full-auto nature, which makes it highly effective in close quarters.” The AMP63 is the fourth pistol for Black Ops Cold War, but it’s more of a hybrid submachine gun.
A double XP weekend is also on the way. It will be active in both Call of Duty: Black Ops Cold War and Warzone from June 4th to June 7th. You can check out the latest patch notes on Black Ops Cold War, here and the latest Warzone patch notes, here.
