Talking to developers isnt like talking to movie stars or pop artists they are gamers like you and me. Dont be intimidated by their stature in the gaming community, just try to keep them interested and get their email.
Write posts and threads on forums, telling deep information (you will learn after signing up) on the game industry and video game testing. Although most gamers can be distasteful, do not submit to this kind of video game treatment. Dont reply to any comments that are in fact distasteful in anyway and always be professional.
Blogging, Start a couple of blogs or a website talking about past projects you have worked on (unless the information you were given by a game company says otherwise). Tell your experience and if you have any schooling to back up your skills. Also provide any specific hardware platforms that you have tested on.
Gaming Community, Although the gaming community is known for sarcasm and ruthless scrutiny, it still can help to be known amongst the fans of gaming. Start to let your job occupation be known and without leaking information, try to convey that you have worked on past games.
Of course, mention that you are at a freelance status and willing to take work from an appropriate company. In order to drive traffic to your new site or blog, link to your address in the signature of your forum posts and your other blogs. Editors and developers might be impressed by your online resume that they might stay in contact with you.
