Red Cloud Rising – An Alternate Reality Game Built on Twilio` Red Cloud Rising is an alternate reality game built by Gyda Arber using Twilio's communication services. The game involves players interacting with two entities, Bydder Financial and the underground group Red Cloud, through voice calls and SMS messages. To achieve this, Arber used Twilio to manage automated phone numbers and voices, which were essential for the game's success. Her fiancé, who has basic PHP skills, helped her code the game's back-end on Twilio within two days. The game was played by 500 people in downtown Manhattan over three months, culminating in its final show.
