Epic Games established the Integrated Partners Program (IPP) to maintain formal business relationships with select companies making cross-platform technologies using Unreal Engine 3.
Under the IPP, Epic provides continuous UE3 source code access and full technical support to members, who in turn agree to provide a high level of technical support for UE3 licensees through Epic’s established support channels. IPP members update their implementations in step with the latest UE3 enhancements and work with Epic on promotional and co-marketing efforts.
The partners program makes it easier for UE3 licensees to incorporate industry-leading middleware and tools into their games. For more information, visit the Integrated Partners Program page at the Unreal Developer Network.
