Operation Strikeback adds many new features and new mechanics, introducing new aliens, new powers and new characters. The Master Aliens - the highest-ranked invaders in the Alien Army - are introduced in this expansion. To win the final battle, the Agents will have to fight the gigantic Wormoon, heavily armored and armed monster with impressive abilities and a terrible bite that can tear an armored agent apart! To fight against these new opponents, the Agency has created new ''toys'' for the agents, including the extremely versatile Power Suits, that improve the Agents' movement, giving him the ability to fly, as well as enhancing his combat abilities. Agents can also be endowed with psionic powers, allowing them to walk through time, cause lethal and critical hits, predict the future, and much more!
Agents are no longer alone in this war, as Operation Strikeback introduces a Non-Player Character (NPC) system, allowing intelligent non-player agents to fight side by side with the GD squad. The Operation Strikeback box includes new miniatures, new cards, new maps, a storybook and a new rulebook.
