In the announcement for the Technical test, Jon “Slothy” Shiring talked about their new matchmaking system improvements, improved play with your friends, and new systems for running their dedicated servers. Additional modes, titans, mechanics, and a new progression system will be available for testing as well.
Respawn is looking to fix any issues that may arise with the multitude of new features, and improve any stutters before the game officially launches. Slothy invites all players to participate:
There is not an official date for the Multiplayer Technical test, but with the launch of Titanfall 2 slated for December, it is possible that we can expect to see the test in the near future so that any issues can be fixed before launch.
