Yep you read that right, the one feature everyone has been missing in IV has finally been reintroduced after almost 14 years! This mod adds full underwater mechanics including diving, unrestricted camera, underwater colors and fog, as well as drowning.
Swimming underwater is closer to SA than V, with the camera direction rotating the player.
The mod has full controller and bindings support, diving underwater is bound to the melee attack key.
Powered by IV-SDK, compatible with game versions 1070 & 1080.

Known issues
- The game's seabed is obviously not made for this mod and includes invisible walls, sudden texture changes and sinkholes, a seabed rework is planned but likely won't be finished anytime soon
