Alone they would be the tiny, lonely booths in the dark corners of the convention hall that nobody visited. However, with their powers combined they form the PAX Indie Megabooth, a collaboration between thirty independent developers working toward the cause of increasing their visibility, and not getting drowned out behind the massive Firefall "booth" (read: it's more like a stadium, really.)
The developers on hand this year include a number of big names in the indie scene as well as some newer initiates. Octodad's Young Horses will be showing Octodad: Dadliest Catch. Gaijin Games will be showing Runner2, and a number of others like Airmech, Steambirds 2, and Yata will be on hand as well.
