Unified Theory Games are looking for writers to help produce fiction for their Enter The Vortex universe.
From their announcement:
Unified Theory Games is inviting aspiring authors to visit the UTG forum and post flash fiction works set within the Vortex Infinite Continua. The nature of the game offers writers a unique opportunity to indulge themselves in any genre or mix of genres. Write of massive airship battles over New London or cyborg dinosaurs roaming the gardens of Babylon. With Vortex, anything is possible. The Basic Battlefield Rules are available as a free download.
Be sure to read the Fiction Guidelines before submitting. It is possible that Unified Theory Games may offer to purchase the rights to publish fictional works for a monetary compensation to use in the upcoming Vortex Core Rules.
