Teamwork makes the dream work in Marvel Rivals, but that doesn't mean solo players are left out in the cold. A wealth of Achievements are designed for lone wolf gameplay. This guide focuses on finding and using the Celestial Codex, a key element in one particularly tricky Achievement.
How To Find the Celestial Codex in Marvel Rivals

Season 1's Chronoverse Saga Achievements in Marvel Rivals present some unique challenges. From emoting as a Norse God to locating a Wakandan statue, the variety is impressive. However, the seemingly straightforward "VENI VIDI V…?" Achievement proves surprisingly difficult.
This Achievement requires locating the Celestial Codex and spraying the nearby terminal. The catch? The Codex only appears on the Klyntar map, and the Achievement is Quick Play exclusive, making its appearance entirely random.
Once on Klyntar, your starting side matters. The Codex is a large object in the attacking team's spawn. If you spawn there, you'll find it quickly. Defenders must wait until the attacking team passes the first checkpoint before accessing the enemy spawn.
How To Use the Celestial Codex in Marvel Rivals
Locating the Codex is only half the battle. Regardless of your starting side, familiarize yourself with the spray function (T on PC, left D-pad on console). Any spray will work on the terminal; liberally applying it ensures a successful completion.
Defenders venturing to the enemy spawn should remain vigilant. While unlikely, an encounter is possible. Mobile characters like Spider-Man and Rocket offer a swift escape route if needed.
Crucially, don't leave the match after completing the Achievement. Abandoning your team is poor form, and more importantly, the Achievement might not register if the game's stats aren't fully logged. Even if you finish quickly, stay and assist your team to victory.
