Age of Empires IV Technical Stress Test This Weekend

Also coming this weekend is an Age of Empires IV Technical Stress Test which will get underway on September 17th at 1:00 pm EDT. This differs from previous beta testing for the RTS sequel as it requires no invitation, and is open to everyone. This page has all the details. Here's word on what will be included in the test:
Most aspects of the game available during this event will be focused on the multiplayer experience. However, you will have the opportunity to play against AI via the Multiplayer Custom Lobby, as well as try out Mission Zero (the game’s tutorial). Given this is a Technical Stress Test, we encourage you to play against others participating. The more data we get from different match-ups across various servers, the more action our development team will be able to take to prep our systems for the big day.

There will be four civilizations available – the English, the Chinese, the Holy Roman Empire and the Abbasid Dynasty – and five different maps.
