The amBX Developer Website now offers free downloads of a PC SDK for amBX, the technology that uses special peripherals to create environmental rumble, wind, and lighting effects for games. This is not very widely supported yet, but freeing up the SDK may help change that. Here's word on this software development kit: "It makes amBX very approachable and this is a major step forward in game development. The whole point of amBX is to immerse the player deeper into the game and the amBX SDK now allows developers to harness and control the most powerful immersion experience available in their games. The SDK makes a rather complex operation very simple at extremely low cost."
