Frontier is an unreleased Sega Dreamcast network-focused sci-fi RPG. It would have been a Dreamcast-exclusive game, developed by Turbine Studios and published by Sega shortly after the console's launch, but was cancelled for unknown reasons.
Frontier's scenario involved exploring a planet populated by threatening alien life forms. To avoid risking their own lives, players had to create genetically modified creatures to take their place in a world of hostile environments, mysterious ruins and monsters each more dangerous than the last. Player progress was determined by the genetic material harvested from fallen enemies.
