Call of Duty Season 5 is winding down, but there's still one last big event happening, as the Numbers event is set to go live across Black Ops Cold War and Warzone on Tuesday, September 21 at 10 AM PT / 1 PM ET.

It's uncertain exactly what will happen during Season 5's Numbers event, but this will be a seasonal event across Black Ops Cold War and Warzone that players can participate in to earn in-game rewards. Treyarch's patch notes for Season 5 Reloaded detailed this upcoming event as including a set of nine Cold War challenges that can be completed in multiplayer or Zombies. Warzone will also receive a unique set of nine challenges to complete, for a total of 18 challenges and 19 rewards to earn during the event. Completing a full set of nine challenges in either game will unlock a Sai melee weapon reward.

This event's storyline revolves around the mysterious Red Doors found on Warzone's Verdansk map and the iconic Black Ops campaign narrative of the brainwashing Numbers program. Warzone players should finally notice some activity around Verdansk's Mobile Broadcast Stations when the update goes live. Raven Software detailed these points of interest in the Season 5 Reloaded patch notes for Warzone, stating, "It is suspected that they will soon begin amplifying the 'Dragovich Program' tapes – A.K.A. the Numbers broadcasts – across the region."
