   STOCKPILE + KNIFE FIGHT 3V3 NOW LIVE
Now that St. Patrick's Day has come and gone, the classic Stockpile mode makes it's debut today in Black Ops Cold War Multiplayer,
along with the launch of Knife Fight 3v3 featuring rotating melee Blueprint loadouts in 3v3 Gunfight.

Combined Arms Moshpit also comes to Quick Play this week, offering a mix of 12v12 Hardpoint, Domination, and Assault modes on Crossroads,
Armada, Miami, and Cartel. And for old-school fans, Throwback Moshpit returns in Core and Hardcore,
featuring a mix of respawn modes on Express, Raid, and Nuketown '84.

E-TOOL WEAPON TUNING
We've seen a lot of love for the new E-Tool melee weapon in Zombies since its release last week,
and we've also heard some requests to give it a little extra TLC in Multiplayer. Today, that wish is granted.

With our latest update, the E-Tool has been upgraded from a 2-hit kill to a 1-hit kill in MP,
and now boasts a faster melee swipe time and an increased boost to movement speed when equipped.
Go forth and bonk head's to your heart's content.(according to me it is amazing now and the swipe time is extremely fast)

NEW LEAGUE PLAY MAPS
As Stage II of the CDL 2021 season kicks off today, we're updating the map pool in League Play to keep things fresh.
Apocalypse now replaces Crossroads Strike in the CDL Hardpoint map rotation,
