A weekly update from Sledgehammer Games has details on a new patch that's now live in Call of Duty: WWII, a major content update which includes new item types including weapon charms and weapon reticles as well as changes to the Quartermaster and Supply Drop system. Activision also announces the commencement of Operation: Shamrock & Awe, a St. Patrick's Day-themed community event that will run until April 3rd. Here are the details:

Shipment 1944
Shipment 1944, a re-imagining of the classic close-quarters Multiplayer map, is free and available in Call of Duty: WWII in early access for Season Pass owners starting today. The map is free and available to all on Friday, March 16.

Leprechaun Hunt Moshpit
The Leprechaun Hunt Moshpit delivers Team Deathmatch, Hardpoint, Kill Confirmed and Domination modes with a twist: a fleet-footed zombie leprechaun hidden in each map. Players who eliminate the terrifying little sprite are rewarded with something better than a pot o’ gold – all of their equipped Scorestreaks full and ready to deploy.

This mode will be available for players as a Featured Public Match playlist during Operation: Shamrock & Awe, offering 2XP from 10:00 am Pacific on March 16 to 10:00 am Pacific on March 19.

New Weapons and Gear
Players will find all-new St. Patrick’s Day-themed gear, including uniforms, helmets, weapon camos and more, only available during Operation: Shamrock & Awe.

As well as new gear, Operation: Shamrock & Awe delivers two all-new weapons to Call of Duty: WWII – the M-38 Submachine Gun and the MG 81 Light Machine Gun. Both weapons have St. Paddy’s Day-themed variants, available only during Operation: Shamrock & Awe, though other variants of both weapons will continue to be available in the game once the community event concludes.
