I'll be watching you, Agent Six. Agent Six of Hearts is back at work. He's sealed inside a torpedo, blasting towards a warship. His mission? To steal canisters containing a weaponised strain of the SARS virus. Before ChaoSonic can use it to wipe out an uprising that is tearing the City apart. But Six has bigger problems. Vanish is still on the loose. So is Retuni Lerke. And a scientist has designed a new weapon. One more dangerous than anything Six has ever seen. One that could wipe out him, the Deck, and anyone else who opposes ChaoSonic for good. Six has to find the weapon, and destroy it. Because ChaoSonic can't always control their creations. He is living proof.
