Respawn:
Happy Season 1 Day! The update is scheduled to go live at 10:00am PST on all platforms that you will need to download. Patch notes are below. I do by best to account for everything but there may be cases where I miss something. It’s not intentional to omit anything from the patch notes. Enjoy!
