Call of Duty: Warzone has introduced fans to Rebirth Island this season. The island is an old toxin manufacturing plant for the Nova-6 gas originally seen in Call of Duty: Black Ops. Call of Duty: Warzone fans can now drop into the same battleground and fight for survival among the ruins of the soviet facility.

By completing a rather lengthy list of challenges, Call of Duty: Warzone players can earn the Hazardous blueprint for the Krig 6 Assault rifle. This blueprint offers players a powerful primary option along with a green and yellow toxic barrel-themed skin.

This blueprint will be usable in both Call of Duty: Warzone and Call of Duty: Black Ops Cold War, but the gun can only be earned through the unique Rebirth Island challenges. There are 16 challenges in total, and some of them will take a ton of time to finish. Thankfully, the challenges are persisting throughout the season, so players have time to grind out more challenging objectives at a casual pace.

Rebirth Island Challenges

Pilot a vehicle for 20 minutes on Rebirth Island Complete any 30 contracts on Rebirth Island Buy 30 Killstreak items on Rebirth Island Collect 200 piles of plunder from the ground on Rebirth Island Open 100 crates on Rebirth Island Collect your loadout 20 times on Rebirth Island Place in the top 30 percent five times on Rebirth Island Get 300 kills with a Common weapon on Rebirth Island Get 30 kills with a legendary weapon on Rebirth Island Get two kills or assists while in a vehicle on Rebirth Island Destroy one vehicle carrying enemies on Rebirth Island Use 50 armor plates on Rebirth Island Place in the 30 percent 15 times on Rebirth Island Place in the top 30 percent 30 times on Rebirth Island Get a kill before the first circle closes one time on Rebirth Island Kill 100 Downed enemies on Rebirth Island

Alongside a unique cosmetic appearance, the Krig 6 Hazardous blueprint comes loaded with a Suppressor, 15" CMV Mil-Spec barrel, SAS Combat Stock, Sillix Holoscout, and a Foregrip. This set of attachments make it a silent long-range weapon with steady ADS speeds. While the optic is always an option, this rifle is still extremely dangerous and can most likely take down many opponents when played in the right hands.

As a side note, the Call of Duty: Warzone Rebirth Island challenges reward a second blueprint through their completion. Once a player completes the “Place in the top 30 percent 30 times on Rebirth Island” challenge, they can earn the Noxious blueprint for the RPD. While not as powerful as the Krig 6 blueprint, it can still pack a punch at long ranges and keep enemy players away while holding down fortified positions.

Call of Duty: Black Ops Cold War is available on PC, PS4, PS5, Xbox One, and Xbox Series X/S.
