An obstacle is exactly what it sounds like. It is a feature that restricts movement and provides protection for a robo while battling in a holosseum. Although some blasts like Wave-type are designed to go through walls, obstacles do not serve as shields from bomb or pod blasts. There are many different varieties of obstacles, some of which can move and be destroyed, but only two major recurring types.
- Walls are generally longer obstacles which defend well against most gun rounds. However, some bombs and pods can overcome walls.
- Crates look like wooden boxes and can be destroyed by gun rounds. They can take approximately 225 damage before exploding. When destroyed, they do not respawn.
