Asterix & Obelix XXL 2: Mission: Las Vegum is an action-adventure game for PC and the PlayStation 2, the sequel of Asterix & Obelix XXL. It was released in 2005 exclusively in Europe, due to the lower popularity of the franchise in the United States and Japan. The game stars the French comic book characters, Asterix and Obelix, and features spoofs to many classic games, in the same fashion that the comics spoof historical characters and make many cultural references. One such example of this is the box art that has a passing resemblance to the one seen in Grand Theft Auto: San Andreas.
A remake called Asterix & Obelix XXL 2: Mission: Wifix was released for the Nintendo DS and PlayStation Portable in 2006, with added touch screen minigames and Wi-Fi functionality.
Julius Caesar, in another plan to conquer Gaul, builds a theme park called Las Vegum, a parody of Las Vegas. Getafix then swears loyalty to Caesar, and goes to Las Vegum. Asterix and Obelix come to his rescue, with the help of a Roman spy named Sam Shieffer, a reference to Sam Fisher from the Splinter Cell series.
Las Vegum is divided in 6 zones: Lutetia, WCW, LuckSore (Luxour), Little Venetia (parody of Venice), Pirate Island, and SeizeUs Palace. Throughout the game, Romans who slightly resemble famous video game heroes (Mario, Sonic the Hedgehog, Crash Bandicoot Rayman, Pacman, Ryu, and Lara Croft) appear as frequent enemies.
