Nuclear Nova Software has launched Liquid Defense, its latest puzzle game for the Mac. Players must work to eliminate all of the incoming water, gas and oil, while simultaneously managing limited resources. The game features 28 different levels, each presenting separate challenges and requiring a unique solution. 3D graphics are used throughout the boards, although gameplay remains two-dimensional.

Liquid Defense can be purchased for $20, or downloaded for free in a limited eight-level trial version. The company intends on expanding the game to work cross-platform, and is promising to offer any future updates at no cost.
