Overwatch's first year one anniversary event is starting today. The event brings three new maps and anniversary specific loot boxes and ends on 12 June. Overwatch will also be free to download and play for the weekend starting on 26 May.
Overwatch is celebrating its first birthday starting today. The event comes with three new maps called Black Forest, Castillo and Necropolis. "Arena maps are small maps built for intense action. Eliminate all enemy players to win a round—and, ultimately, win the match", is how the maps are described in the official announcement.
In addition to the new maps, the event will feature new cosmetic items from special loot boxes commemorating the game's anniversary. These loot boxes contain special anniversary only cosmetic items. Regular loot boxes will recieve new emotes and and items not specific to the event.
Overwatch will host a free trial period during the weekend 23 - 26 May. All of the game's content will be available for free during that time and any items unlocked through play will carry over should the player decide to purchase the game after the free weekend expires.
