Exoplore the city of Los Santos under water
One of the latest community creations for GTA V is a tsunami mod that completely floods Los Santos. The mod is pretty cool as far as atmosphere and interactivity is concerned because it completely changes how people venture about Los Santos.
Various videos have been going around of the flooded city and the tsunami mod that gives the whole game a completely different feel. One of the videos from MkElite does a fine job of showing off what GTA V looks like replicating the 1995 Kevin Costner film, Water World.
