A unique 4-way dice tower stands at the center of this suspenseful cooperative game for 1 to 4 players. Offshore rig, DeepWell-4, has ruptured and is spilling crude oil into the ocean at an alarming rate! Your joint task force must work together as a team to avert an ecological disaster...one which threatens to contaminate marine life and devastate the ecosystem. Oil dice spill out of the tower onto the four quadrants of the game board, constantly creating new threats. Meanwhile, players sails the perimeter to contain the spill, remove what oil they can from the water and save the sea life. An exciting `reverse tower defense` challenge right to the very end.
