The Delta Squad is gone and the Syndicate has been officially deactivated. A war-ravaged world walks a razor-thin wire between peace and chaos.

Old enemies plot to take advantage of the weakened state the planet is in. But before they can, an unexpected group of heroes arrive, calling themselves Olympians. They have come to bring order back to the world, through force if need be.

Darker powers stalk the world as well. Grandmaster Silence is following former Delta members for unknown reasons, and The Zodiac return from the dead to spread chaos over the world.

All of them have one thing in common. They all want revenge against the Delta Squad for their own reasons. And behind it all, an even darker force is pulling the strings.
