So according to the storefront, it was supposed to be released today (December 3rd) at 7pm. It is now 12pm and no updates what so ever.
What’s up with the release?
Reach will release on the 3rd of December at 10AM PST. As of typing this, that’s about 19 hours from now.
Steam in particular (maybe MS Store as well, I’m not sure) has had a few timezone issues so it may display the wrong day/time.
