Beta testing is the midpoint of a game release life cycle. Games are ready to be beta tested when they are functionally complete. During beta testing, the game is tested--played over and over again--by testers to ensure it's highly usable and is free of bugs that could cause problems with game play.
Beta testers are volunteers, or occasionally marginally compensated, gamers who love to play games or desire to enter the industry as professionals at some point in the future.
Play hours upon hours of video games. Ideally, play a variety of games.
Make a list of your favourite video games and the companies that made them.
Regularly check your favourite game websites for calls for beta testers. Additionally, check companies such as PlayStation, Electronic Arts, or Microsoft to see if they are currently recruiting beta testers.
Sign up with companies who are looking for beta game testers, found in Step 3. Usually, you will only be asked for your name and e-mail address, but sometimes you may be asked about your favourite games.
Be patient. Sometimes it can take awhile for a company to use your services. This is often because they have a large amount of volunteer beta game testers. However, with persistence, you will have your opportunity.
Follow through with your commitment once a company asks you to beta test a game. The game industry is a small community. If you do desire to enter the game industry as a professional, it's essential to have a good reputation from the very beginning. With enough experience, you may soon be qualified to enter the field as a professional tester.
Network online and in real life. Post on appropriate game forums, message boards, blogs and social networking sites that you are looking for a chance to beta test a game. Go to gaming events, such as LAN sessions or conventions, and let people know you'd like to be a beta game tester. Be polite to everyone you interact with. You never know if you may be talking to a game company employee who has enough pull to help you get your chance as a beta game tester.
