Zero-G Marines is a 3D, real time, first person action game for the PC. It blends proven game play elements from space combat simulations and squad-based, first person shooters. Add to this; high tech combat suits, customizable tactical and strategic elements, and a plausible world, to create an entirely new and exciting gaming experience. With the use of Event Triggers and in-game cinematics to guide the player through a multi-linear theatre, this game will never play the same twice. Throughout the single-player campaign, you select the mission your team will undertake, the personnel to be involved and the weapons load-out that each will use. Using the tactical interface, the player will direct the efforts of the squad against the zealot forces ranged against you.

As a Zero-G Marine officer, this epic struggle takes you from the orbital mining stations of Mars to the moons of Jupiter. You and your team will be heavily outnumbered and operating in hostile territory, months from friendly forces. Supplies and resources must be captured. Survival depends on all your skill, training, resourcefulness, and courage.

The year is 2353. Action takes place among 6 major space stations in our solar system. A top-secret military bio-chemical research project on Space Station Europa has gone horribly wrong. A small group, known as the Council of 9, lead by a shadowy figure calling himself Nihilo, has seized the facility and used the newly created microbial virus to infect and control the inhabitants. It physically creates a new neuro-transmitter that induces blind obedience and heightened strength and senses. These zealots have quickly taken over 5 space stations, by infecting everyone they can. They now threaten Earth itself. The newly formed elite Zero-G Marines team has been sent to end the threat and retake the stations, using deadly force.
