Grassrivers.

Grassrivers is the wetland region on Rockstar’s tour of Leonida. Its introduction centres on mangroves, water and the uncertainty of what might lie beneath the surface. Alligators are named outright, while the region’s other dangers and discoveries are left vague.

Alongside the mangroves, the region has marshes and buildings on stilts, so its buildings are part of the wetland landscape rather than an ordinary city district. Named settlements, how deep the water runs, any flood system and mapped routes through the marsh have not been revealed.

Rockstar’s captions describe two alligator scenes: armed people posing on an airboat with a dead alligator, and an overhead view of a boat surrounded by living alligators. The posed scene also includes a dead wildcat. The caption calls it simply a wildcat and names no species; the cougar shown in Mount Kalaga is a separate sighting.

Airboats appear again and again in the region’s imagery as part of life on the wetland. A separate caption describes a pickup chased through the swamp by two police cars and a helicopter. The pickup’s model and any mission behind the chase have not been revealed.

The posed dead animals and visible firearms point to outdoor activity in the region, but no hunting rules have been revealed: nothing has been said about rewards, legal restrictions, skinning, animal respawns or a hunting contact. The deadlier predators Rockstar hints at also remain unnamed.
