Venice is a cramped area with enemies that can pop up out of nowhere. There are numerous gondolas throughout the map that can be rode to traverse the canals that split the level roughly down the middle. The Shotgun is strongly recommended!

Boat

In Venice, there is a boat that comes by blue and red base, you can get on it and ride it to a building which has weapons, a body armour, and power-ups. The boat does not appear on Virus.
