WeQuest available for download
WeQuest is a platform for authoring, sharing, and delivering mobile Alternate Reality Games (ARGs) in which geo-location is used to blend real world locations and fictional storyline elements... Thus to play a mobile ARG, one must physically visit locations in the real world. The WeQuest game engine runs on iPhone and includes the ability to interact with virtual characters. WeQuest also contains an end-user authoring tool with which users can create new interactive stories.
