Developer Treyarch continues to expand Call of Duty: Black Ops 4 with updates, and there's a new one available now on PS4, Xbox One, PC that adds a map variant for free. There's also two new modes on the way and plenty more. The new map variant is named Arsenal Sandstorm. As you might deduce from the name, it's a version of Arsenal that has been overtaken by a dangerous desert storm, and it's available for free for all players now. PS4 players have a new mode called Deathmatch Domination to enjoy. Treyarch describes it as a "first-of-its-kind mode for the Black Ops series" in which teams can increase their score by capturing objective points and by killing enemies. It's essentially a cross between Team Deathmatch and Domination, then. Xbox One and PC players aren't totally left out. While they can't enjoy Deathmatch Domination just yet, they do now get to play Infected, which was previously only available to PS4 players and is now live on all platforms. The mode involves infected players running around attempting to pass on their disease to survivors in order to turn them to the infected side. The remainder of the update is primarily made up of balance tweaks--most notably to the Rampart 17 and KN-57 assault rifles--and stability enhancements. You can read the full patch notes below, via Treyarch.Free Arsenal Sandstorm Map As we put the finishing touches on three additional Multiplayer maps launching with our next Operation later this month for Black Ops Pass holders, we're excited to release our newest alternate-weather map free for all players: Arsenal Sandstorm. Hot on the heels of Contraband Hurricane, Arsenal Sandstorm is our most intricate map makeover yet in Black Ops 4. Players will need to adapt their playstyles to waves of sand sweeping across the environment, with limited visibility throughout the facility encouraging shorter-ranged engagements. We're excited to see how player strategies will evolve on Arsenal Sandstorm, now in rotation on all platforms. Deathmatch Domination Debuts on PS4 If you've ever wished your team could play the objective in Domination even if they're just there for the streaks, we've got great news. Introducing Deathmatch Domination on PS4, a first-of-its-kind mode for the Black Ops series. In this new take on Domination, teams now have two ways to earn points toward the score limit: by capturing objectives, and by earning kills throughout the match. No matter how you play, you'll be playing for the team. Get out there and let us know what you think in the comments. Infected Now Live on All Platforms Infected is now live in Multiplayer on all platforms! We've also made some improvements to gameplay and stability, including the addition of 10 seconds to the game clock instead of 30 when a Survivor becomes infected, to help keep matches from running longer than intended. Check out the patch notes below for what's new, and if you're an Infected newbie, be sure to get familiar with the preset Survivor classes so you're ready to hit the ground running... for your life.
