Drox Operative: Invasion of the Ancients is the first expansion for the unique action RPG Drox Operative. It adds ancient invasions, space stations, persistent galaxies, Scavenger race, new Talon, Legion, and Overlord monsters, 19 playable subraces, and much more.

Before the Drox ruled the galaxy, before they were even sentient, there were older races now known as the Ancients. Using their Operatives, the Drox crushed and enslaved most of these races. The rest fled known space. When the Drox turned on their own Operatives, the Drox were utterly destroyed. Newer races emerged and thrived in the power void, never knowing the menace waited. Seizing their chance, the Ancients are invading to take their rightful place in the galaxy, as rulers! Thirsting for revenge, the Ancients can't harm the extinct Drox, but they can crush the next best thing, the Drox Operatives.

The Ancient enemies are back! Can you defend the Drox Operative Guild and younger races against the Invasion of the Ancients?
