In Albion (Parody of London), when Crypto is not in disguise. Citizens scream out, "Where's the bleeding TARDIS?" and "Someone ring the Doctor!" This is referencing Doctor Who as it was majorly popular during the 1960's with both William Hartnell and Patrick Troughton's first and second incarnations of the Doctor. Also when Crypto uses mind control on a citizen to follow they say, "I obey, I obey." referencing the Daleks!
If you die in the game, the number of deaths will influence the last side mission in Takoshima, in which the "boss" will get as many lives as you have lost so far in the game.
In Albion, when Crypto is not in disguise. Citizens mentions the Mysterons. Referencing the villains in Gerry Anderson's Supermarionation series, Captain Scarlet and the Mysterons (1967-68).
