The Wilderness is an arena owned by Janise Keri. It is literally an arena in the wild, with no boundaries. Rost and other bots built for the wilderness are strongest here.
The wilderness has no rings and no boundaries, allowing bots to use the terrain to their advantage. When bots are far from the audiences view, they can see them on a screen. Bots can use the trees to get lost, or use camouflage to avoid detection
It is also one of the places in Real steel: Hijack survival that have IX-9 Bases.
The Wilderness has 3 rules: You cannot use wild animals against each other (though it would be fun), Water areas are off limits, and you can only use small trees to batter other bots
