Mt Chiliad was GTA V's tallest peak and home to one of gaming's longest-running fan mysteries. Leonida won't have anything like it. Here's why and what takes its place.
Why no equivalent
Florida is flat. The highest point in real Florida reaches only 345 feet. Leonida is based on that landscape and couldn't reasonably have a mountain big enough to qualify for Chiliad status.
Verticality will have to come from elsewhere - skylines, bridges, maybe construction zones.
What replaces Chiliad's gameplay
BASE-jumps may come to skyscrapers. Skydives may take place from bridges or ships. The mystery-mountain pattern doesn't carry over - whether GTA 6 has a similar Easter egg tradition has yet to be seen.
