The online beta for NHL 17 is now up and running on Xbox One and PlayStation 4, one day earlier than had been originally scheduled. Emails have gone out to those who signed up for it when open from late June through mid-July containing codes for the 19.2 GB download.
EA Sports Hockey League, Hockey Ultimate Team, and online head-to-head are all featured in the beta which is currently planned to run through August 4. If you need an EASHL club to join on PS4 one has been set up under the name Hit The Pass.
