Surely coincidental with the recent release of rival Diablo III, the Torchlight II Website announces this weekend will be a stress test for Runic's action/RPG sequel, as they will evaluate the burden the game will place on their infrastructure and everyone's mouse buttons (thanks AusGamers via VG247). Here's word:

Hi Everyone! We've been busy squashing bugs and deploying patches - 8, in fact! - since our last update. The Torchlight II beta is going really well, and is nearing its end. But before we go, we're going to do a wide network stress test this weekend! We'll be sending out many more beta codes to those who have already made their Runic Games Account. Haven't signed up yet? Go for it now! Creating your account is always your best chance to receive a beta invite - especially this weekend.

The Beta Weekend will start on Friday, May 18th at 11:00am PDT and go until Tuesday, May 22nd at 11:00am PDT. We will be staggering invitations to let participants know they have been chosen, but you will not be able to play until the start of the Beta Weekend on Friday. This is to help stagger downloading of the game client.

The beta will end shortly after this last big network test. We are going to get the last information we need for stress testing, and then get back to finishing the game! A longer beta means a longer wait until we can ship, and we are eager to finish Torchlight II and get it in your hands. Thanks to all our fans who've supported us, participated in, and promoted the beta. It's incredibly fulfilling to see you guys play the game and enjoy it as much as we do.
