A Guild Wars 2 stress test will take place today between 8pm and midnight, ArenaNet has announced.
"Unlike previous stress tests, we will be actively working on the game during the event, so you might experience connectivity problems or discover features that are not working as designed," explained a Facebook post.
"Any issues you experience are a result of the rigorous conditions of the stress test, and are in no way representative of the state of the game at launch.
"By participating in this stress test, you’re helping us make Guild Wars 2 a better game. Thanks for your cooperation."
Guild Wars 2 launches August 28.
