We are excited to announce that we are now collecting information for those interested in applying for the opportunity to test Star Wars™: The Old Republic™. Our goal is to get feedback to help us make the best game that we can.

We will be selecting testers from the Star Wars: The Old Republic community based on various requirements such as systems specifications, age, and region. Because the testing program requires feedback from within the community, you must have an active Star Wars: The Old Republic (“TOR”) community account to participate (no banned accounts). The testing is limited to members who are 18 years of age or older and requires the acceptance of the Game Testing Agreement included in the TOR community sign-up process. Users that meet the requirements of the test and are selected for inclusion in the test program will be contacted via email (so make sure your email address is up to date!).

Game testing for Star Wars: The Old Republic will be rolled out in several phases over an extended period of time. These test phases will begin with smaller, tightly focused test groups, and later tests will expand.

Want to get your name on the list of potential testers? First, make sure you are a registered member of the Star Wars: The Old Republic community. If you’re not already a member, click here to become one today! Be sure to check the box to indicate you are interested in becoming a tester. If you’re already a member, go to the Game Testing Portal to begin the sign up process.

Please keep in mind that there are no guarantees that you will be selected once you have completed the sign up process. For more information about testing Star Wars: The Old Republic, take time to read the Game Testing FAQ.

We look forward to your help in making Star Wars: The Old Republic a success!
