Grassrivers

Welcome to the Wetlands. The untamable jewel of Leonida's crown. You never know what lies beneath the surface of this primordial expanse. The gators may be the most famous attraction, but there are far deadlier predators and weirder discoveries among the mangroves.

The Grassrivers is Leonida's largest wilderness biome, stretching across the southern third of the state between Vice-Dale and the Leonida Keys. The region is built on the same model as the real Florida Everglades, with mangrove tunnels, sawgrass prairies, hammock islands, and airboat trails. Wildlife is the headline attraction, with alligators, snakes, raccoons, bobcats, and herons all confirmed by Rockstar's official wildlife chart. The Grassrivers is also the most likely setting for hidden missions, toxic waste plots, and offbeat secondary characters such as swamp hermits and back-country meth chemists, in the tradition of GTA V's Sandy Shores and Trevor's Trailer.

Grassrivers is drawn from Florida Everglades. Rockstar has historically built its game worlds as semi-faithful caricatures of real places, picking out the strongest visual and cultural cues and reshaping them into a satirical version of America. Expect recognisable streets, signage references, and visual gags throughout.
