Arena
The Arena for the 500th Hunger Games is a combination of both biomes inspired by The Capitol and the Districts, and replicas of past Arenas that The Capitol has voted via polls as their favourites. It is by far the largest arena ever.

The climates and muttation ranges work similarly to (and are somewhat inspired by) the biome mechanics of Minecraft; the climates and muttation ranges are mostly restricted to the biomes that they're in, with some exceptions.

The arena is shaped like a square, and an ocean, which is technically its own biome, separates the island biomes from the mainland biomes.
