Eddie Plant (Peter Dinklage) knows the codes to activate the glitches in the classic arcade games. The aliens get wind of this after the Pac-Man attack, and mass-release characters from all the 1980's arcade games, including a human rendering of Ludlow's digital crush Lady Lisa (Ashley Benson).
Sam Brenner (Adam Sandler), Lt. Col. Violet van Patten (Michelle Monaghan), and President Cooper (Kevin James), board the mother ship with Q-Bert, an alien who is against the war. They face off inside against Donkey Kong, who is ultimately defeated by Sam.
The world is saved, and the aliens return to their place of origin, save for Q-Bert, who reshapes himself as Lady Lisa to live happily ever after with Ludlow.
