Alien Devastation 3

From Tardis Wiki, the free Doctor Who reference

Alien Devastation 3 was a video game that Luke Smith and Clyde Langer loved to play.

In the 2000s, they were taking each other on in the game and Luke blasted the alien invaders apart. Clyde just told Luke that he let him win when Sister Helena rang the doorbell and Luke had to open it. (PROSE: Eye of the Gorgon)

In 2009, as Clyde saw the International Gallery for the first time he told Luke and Rani that this place was like finding the way through Level Four of Alien Devastation 3. (TV: Mona Lisa's Revenge)
