Demo of this beautiful game is finally available for Linux.
OilRush is a real-time strategy game based on group control. It offers mechanics of a classical RTS combined with a Tower Wars genre: control the upgrade of production platforms as well as their defence forces, and send battle groups of naval and air units to capture enemy platforms and oil rigs.
In a post-apocalyptic flooded world there are two things running short: oil and time. The last survivors in a desperate desire to seize control and dominate the enemy have started the naval warfare that turned the whole world into one large battlefield. In these harsh and cruel times, oil is thicker than blood.
