Rolling Fortress is a skill that increases the duration of the Shield Powerup. This powerup works in all multiplayer and single-player races. This skill is very useful because after learning how Traffic Magnets work, it is much easier to dodge them. The juggernaut powerup also works well to plow through attracted cars and has a much shorter cooldown period.
