With retail stores selling Overwatch today, it’s been revealed that the day one update (listed as 1.02 on PlayStation 4) is a 9.66GB download. Reports also suggest the Xbox One update is around the same size.

As the PS4’s Update History shows, the Overwatch patch adds new modes, new maps, and more:

New Escort Map: Route 66

New Control Map: Ilios

New Play Mode: Custom Game

New Play Mode: Competitive Play

New Play Mode: Weekly Brawl!

New Feature: Highlights

Updated new player experience

If you’re getting the digital version of Overwatch, pre-loading is available on all three platforms. You’ll then be able to play it at 4pm PT/7pm ET today when the servers go live.

Asked if you can use the same files from the beta for full release, Blizzard replied, “For PC, yes. It will auto-update. For consoles it’s a separate file.”

According to an Overwatch news feed, the first big content update should arrive late next month with the competitive mode.
