Gearbox Software has been a Co-Optimus community darling ever since they released the mighty Borderlands. You may have heard that there is an upcoming sequel, titled -wait for it- Borderlands 2. Gearbox is a fan friendly company, and they want to know what you liked about the original Borderlands. You can follow this link and help them out with a survey. Complete the survey and you'll be entered into a drawing for some Gearbox swag.
The survey will take you about two minutes, unless you're some type of crazy person who doesn't test well. The questions are about weapons, characters, vehicles, you know, survey questions. The best part is that there's a comment section at the end, where you can compose a love letter to Gearbox, and beg them for free copies of Borderlands 2.
