Season 3 of Call of Duty: Black Ops Cold War and Warzone is home to plenty of exciting new content for players to sink their teeth into, but among the most exciting additions are the three brand new weapons: PPSh-41, Swiss K31 sniper rifle, and Ballistic Knife.

Tons of exciting new content has been added to Warzone and Black Ops Cold War for Season 3, and as per usual, there are three brand new weapons in both games, all of which are available to players for free.

Headlining the trio is the iconic PPSh-41, which most will remember from the Call of Duty’s WWII title. This fan fan-favorite SMG also features alongside the Swiss K31 Sniper Rifle and Ballistic Knife.

Whether any of these weapons will be able to switch up the current Warzone or Cold War metas remains to be seen, but you’ll definitely want to get your hands on them as quickly as possible.

The PPSh is the first gun to be unlocked in Season 3 and only requires players to reach Tier 15 of the Season Three Battle Pass. Once this lighting-fast SMG has been unlocked, you’ll be able to use it in Warzone and Black Ops Cold War’s multiplayer modes. 

While the gun’s damage per shot may be “moderate,” its rapid-fire, high-capacity capabilities can quickly chew through many a foe, making it very effective in close-quarters situations.

The next weapon to be unlocked in Warzone’s Season 3 is the Swiss K31 Sniper Rifle, for which you’ll need to reach Tier 31 in the Season 3 Battle Pass.

This bolt-action sniper rifle boasts exceptional accuracy, as well as fast rechamber and aiming speeds with a large ammo capacity. Those that enjoy using the Kar98k Marksman Rifle will definitely want to add this Swiss sniper to their arsenal.

This spring-action knife launcher was first introduced in the original Black Ops title. Not only can this deadly melee weapon be used as a standard knife, but it can also silently fire lethal retrievable blades. While skilled players will be able to land ranged shots, this weapon is often best reserved for close-quarters fights. 

The Ballistic Knife is available in-game, though you have to complete a challenge to get your hands on it. You’ll need to find a ‘One Shot, One Kill’ medal and a melee kill in the same life across 15 different matches.
