REX: Bushwhacked

 is a challenge in Risk of Rain 2. It is completed as REX by completing an entire Teleporter Event while under 50% Health.

Tips

 * The Shrine of Blood can help to reduce your health below 50% before the teleporter event.
 * You can use turrets (or drones, but they aren't as good) to protect you during the teleporter event, while you use Seed Barrage to keep your health below 50%.
