The Dark Souls III team is looking for PlayStation 4 owners with internet access to join up for several network stress test events. The events will take place regionally during October, with players selected in a "lottery" type drawing. Applicants will be testing game systems and balance, helping the team track bugs, helping to evaluate the load on servers and more.
You can check out the dates and regional information here or head straight to the application page here.
