The Platypus is a cargo ship in Grand Theft Auto IV. Niko Bellic served as a crew-member for several months, along with Hossan Ramzy. It was involved in smuggling operations, including diamonds, heroin and sports cars. When Niko arrives aboard the Platypus in East Hook, Liberty City, the ship is carrying immigrants from across Europe, including Spain, Germany, Egypt, Taiwan and Serbia.
According to news reports, the captain and entire crew of the Platypus disappeared shortly after the ship docked and the passengers disembarked. One of the crew was found in the Humboldt River with whip scars on his back - apparently the man who was engaging in sado-masochism with a woman as the ship was docking. The ship remains docked in Broker throughout the game and, if Niko chooses to exact his revenge on Dimitri Rascalov, is the setting for A Dish Served Cold, suggesting Dimitri intended to steal it and escape America. After this he calls Roman to tell him that "it ended where it began".
During The Lost and Damned, the diamonds during the main story came from the Platypus when Anthony Prince attempted to purchase them from one of the ship's crew, the cook. When the deal was done, Johnny Klebitz and The Lost ambushed the deal and stole the diamonds after killing Tony's boyfriend Evan Moss
The Platypus is also included in the Bomb Da Base II mode of GTA IV's multiplayer. After stealing a Securicar loaded with explosives, a helicopter flies to the Platypus. Arriving at the Platypus, a heavy gun battle begins. This is similar to the Revenge mission, however the Platypus ship is now under control of the Albanians. Two bombs must be planted on either the upper or lower levels of the ship while gunning down Albanians. The multiplayer team must then escape the ship before the explosion.
If the multiplayer storyline is canon with the campaign, that would mean the Platypus is no more.
