Each Warrior has their own unique terrain that they have adapted to. In simulated battles, the two warriors have to use their own territory while crossing into the enemy's territory. Most territories shown in the simulation are similar but some are entirely different.
Season 3 showed many terrains in the sim; forrest, desert/tundra, mountain, open plains, jungle, indoor, hills, swamp and city streets.
