- “Control? This is Noble One. Spire One is green, and you're free to engage. Have a nice day.”
According to Auntie Dot, Spire One was linked to a Covenant Supercarrier, the Long Night of Solace. Spire One provided various different functions that included: shielding infantry, providing cover from radar, serving as a teleporter terminus for Phantoms and Spirits, and generating a cloak for the Long Night of Solace. Spire One was destroyed on August 12, 2552 by the frigate Grafton during a UNSC counterattack.
- Spire One is also the setting for the multiplayer map, Spire.
- It is extremely simple to skyjack one of the Banshees on Tip of the Spear, due to its low flying, whilst they are attacking Jorge-052. It only requires a player to use a jetpack to boost up to the Banshee.
- Also the AI of the Banshee Pilots in Tip of the Spear are apparently not suited for the terrain of the area as they will oftentimes get stuck in a rock formation or under the pipes.
