About the game
The Oil Blue: Steam Legacy Edition takes place in a future where oil has become desperately scarce. Players lead a crew back out onto the ocean to reactivate abandoned island drilling rigs on behalf of the UOO, the planet's largest oil supplier. Conditions on board are harsh, and there's no turning back once the job begins. Vertigo Gaming Inc. both developed and published the title in 2015.
