New Overwatch beta patch introduces few new things: map, player mode, features.
New Escort Map: Route 66
Though the travelers and road trippers who used to cross the US on historic Route 66 are gone, the Main Street of America still stands, a testament to a simpler time. The gas stations, roadside shops, and cafes have gone into disuse, and the fabled Deadlock Gorge is mostly seen from the comfort of transcontinental train cars. But amid the fading monuments of that earlier era, the outlaws of the Deadlock Gang are planning their biggest heist yet.
New Play Mode: Weekly Brawl!
Similar to its namesake feature in Hearthstone, Weekly Brawls are a fun, alternative way to play Overwatch.
For example: In one Weekly Brawl, you’ll only be able to play Soldier: 76, while in another Weekly Brawl, a random hero will be selected for you each time you respawn. Other Weekly Brawls will restrict you to Support heroes only, or Tank heroes only, or Defense heroes only—and more!
New Feature: Highlights
To complement Play of the Game feature, personal gameplay “highlights” may now be surfaced to players via the main menu after they’ve completed at least one match. The game can currently store up to five of the most recent highlights from your active gaming session.
