Hitman 2 has tons of Easter eggs but none is compared to this one. You can ride a dolphin to exit Hitman 2’s Miami mission and it allows Agent 47 to escape.
To unlock this Easter egg player has to complete the mission in a very specific way.
After becoming a part of rival pit crew and disguise as a mechanic, you have to sneak into security office nearby. There, you'll find a code hidden away for the safe that hides a car bomb. From there, you're going to need to take out a Kronstadt mechanic in order to steal his uniform. Once the uniform is donned, attack the discovered bomb to Sierra Knox's car.
Next up, you have to head to the kitchen and grab a fish. Then you need to attach the car bomb to Sierra Knox’s car and call Robert Knox to tell him you’ve done so.
Pass him the bomb trigger when you meet up, then push him to his death to complete the contract. From there, you need to head to the dolphin fountains, pull out the fish, and run around between the tiles in a specific pattern.
Hitman 2 is available now on Xbox One, PlayStation 4, and PC.
