Additionally, the previous Elden Ring network test had five three-hour long test sessions, so youll have multiple opportunities to play.Your main goal as a tester is to take note of any issues that you run into, and since it is a test, youll most likely find a few bugs here and there. The test is somewhat reflective of what the final product may look like, but it is in no way complete!As Elden Ring Nightreign is a co-op game, a big focus of the test will most likely be the games multiplayer features and the server load, so there may be a few connectivity hiccups.With Nightreign being a roguelike, youll experience its gameplay loop of success and defeat, its progression system. However, progression may be tied to the hero youre playing.
