Blizzard has announced the final stress test for Overwatch.
Along with the extensive closed beta that not many were invited too, Blizzard has been conducting several stress test weekends. Prior to the weekends more invites are sent out to players who have opted in for a chance at the beta, and encourages them to download the game client before the days that they will be allowed to play.
“To help us get the most out of this testing phase, we will be flagging accounts for the Beta Test Weekend beginning in the afternoon Pacific Time on Thursday, April 14. […] Once flagged, we encourage all new recruits to download and install the beta client so you can be ready for action once the stress test officially begins.”
