Unlocking the Celestial Codex Achievement in Marvel Rivals: A Step-by-Step Guide
Marvel Rivals encourages teamwork, but solo players still have plenty to accomplish, especially with its extensive list of solo Achievements. This guide focuses on the VENI VIDI V…? Achievement, which requires locating and interacting with the Celestial Codex.

The Celestial Codex is exclusively found on the Klyntar map, accessible only through Quick Play matches. This makes completing the Achievement a matter of chance, as map selection is random.
Upon entering a Klyntar match, your starting position is crucial. The Codex is a large object situated in the attacking team's spawn area. If you spawn on the attacking side, locating it is straightforward. However, if you're on the defending side, you'll need to wait until the opposing team advances past the first checkpoint before venturing into their spawn area.
Finding the Codex is only the first step. You must then use a spray paint on the nearby terminal. Any spray will suffice; liberally apply it to ensure successful registration. The spray button is 'T' on PC and the left D-pad button on consoles.
Defending players venturing into the enemy spawn should remain vigilant. While unlikely, an encounter with an opponent is possible. Using highly mobile characters like Spider-Man or Rocket is recommended for a swift escape if needed.
Avoid leaving the match prematurely after completing the Achievement. This is detrimental to your team and may prevent the Achievement from registering due to incomplete game stat logging. Stay until the match concludes to ensure proper tracking.
