Grand Theft Auto: London, 1969 (1999 various platforms)
The first extension pack for the Grand Theft Auto series was set in London and involved thirty-two new missions and contained thirty brand new vehicles. The plot of GTA: London is the same as the first game as it involves the player having to work their way into the world of organised crime. The way to activate the mission and the weapons were also the same due to the game using the same engine and format as Grand Theft Auto.
Grand Theft Auto: London, 1961 (1999 PC)
The earliest game in the Grand Theft Auto series is also the second mission pack extension in the series. As it is an expansion pack, it requires both GTA 1 and GTA: London 1969 to play and as it shares the same engine as the previous games, the graphics are very similar. As with its predecessor, London 1961 has a selection of new missions, twenty-two brand new vehicles and unlike London 1969, features a new cut scene and a death match map that was based on Manchester. GTA: London 1961 is the least-known game in the GTA series due to the developers limited promotion of the game.
