Marvel Rivals Celestial Codex: How I Unlocked the Veni Vidi V…? Achievement

I have chased a lot of weird collectibles in hero shooters, but the Celestial Codex in Marvel Rivals might be one of the strangest. During a 2026 revisit to the Chronoverse Saga, I found that this black mass still sits in the Klyntar: Symbiotic Surface map, quietly waiting for a player with a spray and a little patience. The reward is the Veni Vidi V…? achievement, a trophy that lives under the Chronoverse Saga section of the gallery. When I first heard about it, I assumed there would be a puzzle, a hidden terminal, or maybe a boss. Honestly, I nearly sprinted past the thing. Instead, the solution is almost embarrassingly simple: spray at the base of the giant mass in the Attacker Spawn. That is it. No sweat, right? Well, there are a few timing details that can trip you up.

Where the Celestial Codex Appears

The Celestial Codex is located in the Klyntar: Symbiotic Surface map. I can confirm that the massive black mass is in the Attacker Spawn. It is hard to miss once you are inside, but it is easy to ignore if you are focused on the match. The codex is not a pickup you can grab with a button prompt. To turn it into a collectible item, you need to spray at its base. That action also unlocks the Veni Vidi V…? achievement. The whole task is simple for an attacker because the location is already in your spawn room. Just remember to place the spray before the battle breaks out. I made the mistake of waiting until the last second, and I had to scramble back before the doors opened. Do not leave the match early, either. Leaving early will render the task incomplete.

The Attacker Route Is Easy, but Timing Matters

For attackers, this is a low-stress errand. I spawned in, walked up to the black mass, and sprayed at the base. The achievement did not pop immediately in my case, but it appeared before the match ended. That is the key detail: complete the match. I have seen players try to rush the spray and then quit, and that is a bad idea. The Veni Vidi V…? trophy is tied to finishing the job, not just touching the object. Here’s the kicker: the codex is so close to the spawn that you can do the spray and still be ready for the first fight. It is one of the few secrets in Marvel Rivals that does not require a guide, a hidden route, or a coordinated team. You just need to know where to look.

Defenders Need a Little Stealth

The same rules apply to defenders aiming to unlock the Veni Vidi V…? achievement, but the route is less direct. The enemy spawn might be inaccessible at the beginning, so you have to wait until the enemy captures the point. I found that the spawn switches once they start pushing the convoy. At that point, you can sneak past the opponents and reach the Celestial Codex’s location. The actual challenge is avoiding a fight along the way. Heroes like Invisible Woman or Loki are ideal for this task because they can use their invisibility to move around the map undetected. I used Invisible Woman and treated the whole thing like a sneaky errand run. It felt ridiculous in a good way. I slipped in, sprayed the base, and slipped out before anyone noticed. That said, you still need to complete the match. Do not treat this as a quick in-and-out. If you leave early, the task can be rendered incomplete.

Achievement and Chronoverse Saga Rewards

The Veni Vidi V…? achievement pops up under the Chronoverse Saga section of the trophy gallery. It should be unlocked once you complete the spray task, before completing the match. The Chronoverse Saga also includes challenges that players can complete to earn points. In Season 1 of Marvel Rivals, those points could be used to unlock the following rewards:

As of 2026, Marvel Rivals has moved through several seasons, but the Celestial Codex remains a favorite piece of trivia for completionists. The collectible and its lore can be viewed from the Inventory. I checked the Store option and found the collectible listed there, along with the rest of the Chronoverse Saga rewards. The two 200 Units entries are separate currency rewards, which is a nice bonus for players who are already hunting achievements. The codex itself is not a gameplay-changing item. It is a collectible, a trophy, and a small piece of lore. For me, that is enough. I like when a game hides something silly in plain sight and lets players feel clever for noticing it.

Final Thoughts From My Own Matches

For a completionist, the Celestial Codex is a low-effort, high-satisfaction trophy. It is also a reminder that Marvel Rivals hides some of its best secrets in the spawn room. I will leave the rest to your own experiment. If you see a giant black mass in spawn, do not ignore it. Spray first, fight later, and finish the match. That is how I added the Celestial Codex to my inventory and checked another box in the Chronoverse Saga. It took me longer to write this guide than to complete the task, and I mean that as a compliment to the game’s strange little secret. 🕹️
