Earlier this week, Sledgehammer Games rolled out a massive update for Call of Duty: WWII. As well as the usual bug fixes and gameplay improvements, the main feature of the update was the introduction of the Attack of the Undead community event. In this event, zombies have crossed over into multiplayer, bringing with them three new multiplayer modes, new weapons, a limited-time multiplayer map, themed gear, and a new community challenge.One of the three new multiplayer modes will be introduced each week. The current mode is Infected, where one player begins as a zombie. Their objective is to infect as many survivors as possible, while everybody else tries to stop them. The zombies win if everybody is infected before the timer runs out. The survivors win if they mange to kill all of the zombies.On June 5th, Hordepoint will be introduced into the mix. Adding a twist to the traditional Hardpoint mode, the winning team is the one who can defend the point from both the opposition and the zombies. Then, on June 12th, Relic of the Undead will be the new game mode. The player who can keep the zombie relic away from their opponents for the longest amount of time is the winner.Throughout the duration of the event, the zombie Groesten Haus map will be playable in multiplayer modes. New limited-time modes have been created for the tight map, the location for the first appearance of Nazi Zombies in The Final Reich.Captain Butcher returns with seven new weapons — five ranged and two melee. The ranged weapons are the Blunderbuss, the Nambu Type 2 SMG, the Lever Action Sniper Rifle, the PTRS-41 Sniper Rifle, and the Stinger LMG. The new melee weapons are the Fire Axe and a "big f******" Claymore sword. He also holds limited-time Collection Reward weapon variants until the event ends. New themed gear includes Commando for the Airborne Division, Russian Engineer for the Armored Division, French Legionnaire for the Infantry Division, and Undead Warden for all divisions.Finally, there's a new community challenge where all players have to do is to kill 3 billion zombies between them in either the multiplayer modes or Nazi Zombies mode. The rewards include the Tesla Gun Weapon that can already be found in the limited time game modes introduced with the community event. Take a look at the trailer below to see what exactly you can expect over the next few weeks.If you're more interested in learning what the patch changed, you can find the patch notes in the spoiler below.*** Spoiler - click to reveal ***FEATURE UPDATES Attack of the Undead Community Event is live!

We’ve adjusted how Saboteur interacts with the Flanker Basic Training so that it no longer cancels it out and has its own detonation time.Rifle Grenade Attachment:Buffed explosive min and max damage Old: 25 min damage and 120 max damage New: 35 min damage and 125 max damage Explanation: The Rifle Grenade was relatively weak and wasn’t as useful as we intended it to be, so this buff should make it a more viable option.Launched Basic Training:Buffed by increasing launcher damage when using Launched Basic Training New: Launchers now deal 30% more damage with Launched Basic Training than before Explanation: When we rolled out our Divisions Overhaul in April, we nerfed the strength of launchers to ensure that they wouldn’t dominate the play space and would rather be used primarily to take out Scorestreaks. This change makes this Basic Training and the use of launches a better option for a wider variety of playstyles.Bayonet Charge/Attachment:Added a sprint speed increase while charging New: +4% sprint speed Explanation: With the addition of unlimited sprint for all, the Bayonet Charge lost its movement advantage, so we added a speed increase while charging that makes it more viable for closing space between you and an enemy.Tactical Knife Attachment:Buffed by adding a melee speed increase when you have Tactical Knife Attachment equipped New: 15% quicker than standard melee speed Explanation: Now that Tactical Knife fills an Attachment slot, there is less of a reason to use it over a melee weapon. This small buff makes it more usable.Shifty Basic Training:Buffed by increasing number of additional Pistol Attachments Old: 1 additional pistol attachment New: 2 additional pistol attachments Explanation: Shifty Basic Training is currently on the low-end of Basic Training usage. This change should make using pistols more viable outside of the Infantry Division.GAMEBATTLES/CoDCASTER/ESPORTS MODE Fixed issue in GameBattles where Restricted Items were displaying in default loadouts Fixed issue where when spectating in CoDCaster mode, players with Infantry Division equipped will not appear to have a Division patch in the Division info displayZOMBIES Fixed UI issues with the Dynamo variant for Nazi Zombies Fixed functionality and UI issues with post-match lobbies Fixed UI issue where notifications where not populating properly Fixed issue in The Shadowed Throne where ammo was not able to be replenished for the Ripsaw Fixed issue in The Shadowed Throne where players were able to kill to kill the human, as well as the zombie, in vignettes Fixed various map exploits on The Shadowed Throne Fixed issue where splitscreen players lost functionality when simultaneously pressing Back and Select Fixed issues with completing certain quests in The Shadowed Throne Fixed UI issue where incorrect rarities were displaying for Supply Drop item cardsBoth the patch and the event are available now, the latter running until June 26th.
