Bandai Namco’s network beta for Dark Souls 3 is currently available for North American players on the PlayStation Store for PS4. It’s not an open beta however – those who signed up for beta access will receive a code for the same, allowing access.
However, you also have to wait for the scheduled network stress tests as well. These tests will start on October 16th and end on October 18th. For each day, the network test will start at 8 PM and end at 11 PM CEST. If you’ve received a network beta code, then these are the times you’ll have to play. Network test schedules for Europe haven’t been revealed yet.
Dark Souls 3 will be releasing on March 24th 2016 in Japan for Xbox One, PS4 and PC. It will also be out in April for North America and Europe though a concrete release date has yet to be provided. Stay tuned for more information on Dark Souls 3, especially with regards to its network stress tests.
