Call of Duty: WWII is rolling out its latest community event, along with a long list of content updates and additions for players. This includes a new re-imagining of a classic multiplayer map and a game mode where you hunt a terrifying enemy: a leprechaun.

The St. Patrick’s Day event, called Shamrock & Awe, starts now and goes until April 3. There is St. Patrick's Day-themed gear, which you can see in the video above, and the introduction of two new weapons: the M-38 Submachine Gun and the MG 81 Light Machine Gun. There are St. Patrick's Day variants of both guns, available for a limited time, but other variants of the guns will be around after the community event ends.
