Sly 5: Thieves Forever Part 1
The story of this game begins in Ancient Egypt, where Sly wakes to discover he is lost in the past. He is almost arrested by some guards, but escapes and ends up at a cave. It is inside this cave that he meets a mysterious man calling himself Raul Wolfgang. He claims that he knows of Sly's predicament, and that he believes that Le Paradox had an accomplice, who is still intent on bringing down the Cooper Clan. He tells Sly that he has a time machine of his own, and that the two can use it to help Sly's ancestors. Sly, who is torn between trying to return home and protect his legacy, reluctantly agrees to work with this stranger to at least save his ancestor from the Egyptian time period, Slytunkhamen III. His whereabouts are currently unknown, and with the emergence of a tyrannical pharaoh named Osiran, it is presumed that he is in hiding. Osiran, who seems to possess some futuristic technology, has carved his face into the sphinx and the pyramids.
Meanwhile, back in the present day, Bentley notices a news report from the pyramids where Osiran's face is now carved into them. Alarmed, he contacts Dimitri who informs him that the Thievius Raccoonus has been altered on the page of Slytunkhamen. Determined to travel back to Egypt, Bentley rounds up the full gang including the Panda King, who agree to work together to break into the Parisian museum and steal the Eye of Anubis so that they may travel back in time.
Back in Ancient Egypt, Sly and Wolfgang have located Slytunkhamen, who is locked in a crypt beneath the Grand Pyramid. Realising the pyramid is booby trapped with futuristic technology; Sly concludes that he will require the use of a Mummy Costume. Stealing the parts of it from underneath Osiran's guards' noses, he uses its ability to sink beneath sand and rescues Slytunkhamen, who believes that he is the god of death Anubis. Slytunkhamen with great reluctance joins Sly and Wolfgang back at the cave they are using as a safehouse. The three plot to use Slytunkhamens stealth (he has the ability to turn into a sarcophagus at will and has shadow power) to destroy the Grand pyramid where Osiran is held out.
Back in the present day, the Cooper Gang break into the museum using the Panda Kings fireworks and Dimitri's scuba suit in the sewers. Absconding with the Eye of Anubis, they are cornered by Carmelita on the way out. Realising their desperation to find Sly, she joins them and covers their escape. When the gang arrive back at the safehouse, they are horrified to discover the place ransacked. The cooper van has been stolen, as well as the Clockwerk Eye, the last remaining piece of Clockwerk, collected by the gang on their travels in the Ice Age. Murray is distraught and sets out to find the van before he can be stopped. Bentley begins to research leads.
In Egypt, Slytunkhamen is successful in gaining entry to the Grand Pyramid. He signals Sly, who pickpockets guards to gain entrance to the vault entrance. Sly becomes angry when Wolfgang is late for his side of the bargain, but when he appears he calms down. With the aid of a three-way combined attack, the Grand pyramid falls to rubble. Osiran, enraged, orders his slaves to drain the Nile so the people nearby will be forced to reveal the culprits. Sly and Slytunkhamen free the slaves working the pumps, whereupon Slytunkhamen confesses that he doubted Sly, but now proudly sees him as a Cooper. Osiran's operation is now falling apart, and it is revealed that he has a massive laser inside his Sphinx, and plans to use it to raze Cairo to the ground in vengeance for his pyramid's destruction. Upon reaching the sphinx's top, Sly confronts him where it is revealed that he has a "benefactor". It is revealed that Osiran is from the time period, but was born poor on the streets of Cairo. Upon meeting a mysterious individual from the future, he has been given power and wealth and subsequently became the leader of Egypt. Sly battles him using the Mummy costume to become impervious to his sand attacks. Eventually defeated, Osiran falls from the top of the Sphinx, seemingly to his death. Slytunkhamen disables the death ray, and is hailed a hero by Cairo's citizens. He shakes hands with Sly, saying that he will soon become infamous in the minds of the people when he steals their gold. He tells Sly that he is proud to be related to him, but that he shouldn't trust Wolfgang, as he has a bad feeling about him.
As Sly returns to the cave hideout, Wolfgang shows him his handheld time machine. It is revealed that Wolfgang is from a far future, long after Sly's own time. He informs Sly that his ancestor, Henrietta One-Eyed Cooper is in trouble, and (wary of Slytunkhamen's warning) the pair travel to seventeenth-century Caribbean to help her. As the pair leave, a pan of the Egyptian landscape reveals a mysterious owl shape seated on the top of the pyramid, watching closely with ominous yellow eyes…
