The UDK Website now offers the new May beta of the Unreal Development Kit, offering an updated edition of this free SDK for creating games with Epic's Unreal Engine 3. Here's the deal: "This month, we’d like to share a case study on using UDK for architectural previsualization. This story details how one university student created a highly realistic, interactive virtual walkthrough of a modern architectural schematic using UDK. In his first encounter with Unreal Engine 3, Luigi Russo created 'realistically scaled models that you can walk inside, offering the best possible view of the project. UDK was a lot easier to learn than I could have imagined'." The download is mirrored on Gamer's Hell.
