Addons - Innovators in Science

Innovators in Science, previously known as the Tier 3 Development Team, is a group of dedicated Portal fans bent on bringing to light the best possible Portal mod they can make. They all met over Steam User Forums and all share a love of Valve, especially Portal! They are currently working on a Portal and Portal 2 mod called Tier 3. They are going to get around to changing the logo and the screenshot soon, as they have no official logo yet and the screenshot is slightly outdated (they keep most of their work to themselves, so new screenshots haven't been released yet.)
