With Call of Duty: Black Ops Cold War Season 3 just around the corner, Treyarch has started a double XP weekend to help players get those last minute Prestige milestones before the new levels arrive. This week’s patch also introduced the heavy-duty ZRG 20mm sniper rifle as the sixth new weapon for Season Two.
The four day double XP weekend is live already and will run until 10AM PT on Monday, April 12. The weekend accompanies the latest patch to be released for the game, introducing the sixth new weapon of Season Two: the ZRG 20mm sniper rifle. As the name suggests, the rifle fires 20mm rounds making it the most powerful sniper rifle in the game. The weapon can be earned through the usual in-game challenge, or purchased through the Jackpot Sniper bundle in both  Black Ops Cold War and Warzone. Gunsmith Customs and Gunfight Tournaments were also introduced to multiplayer this week, the latter coming with exclusive rewards. Gunfight Blueprints also had a Season Two Reloaded update. Meanwhile, plenty of gameplay improvements and bug fixes were added to Zombies Outbreak, Dead Ops Arcade 3, and Onslaught. You can see the full patch notes below:
