ULRTA POWERUP!! is a powerup that cannot be ordered alongside others due to its different method of spawning. It was added to Fortress Blast in version 4.0 and is a completely original powerup. It is an exceedingly rare powerup, having a default spawning chance of 0.1%, which is controlled by the ConVar

- Super Speed, but it lasts for 10 seconds instead of 8.
- Mega Mann, but the user receives the maximum health possible and is not resized.
- Frost Touch, but with no damage resistance for frozen victims.
- Full critical hits.
