Wrap up the Cerebro Database Seasonal Event in Marvel Rivals Season 2 by completing the Event 4 missions with this guide.

The Cerebro Database Event 4 is now live in Marvel Rivals. This is the last update for the Seasonal Event of Season 2.0. After this, players can complete all seasonal challenges and claim rewards until it ends in two weeks. This also wraps up the four sets that we needed to complete to get the Flora Maiden skin for Mantis.
All Cerebro Database Event 4 Challenges in Marvel Rivals
There are a total of nine challenges presented in a grid form in each event of the Cerebro Database Seasonal Event. Event 4, just like Event 1, Event 2, and Event 3, has straight-forward challenges that players can complete in Competitive, Quick Match, or Practice vs AI. The challenges go as follows, in the same grid pattern:
Score 3 Double KOs in Quick Match, Competitive, or Practice vs AI | Collect 10 Health Packs in Quick Match, Competitive, or Practice vs AI | Take 30,000 Damage as any Vanguard in Quick Match, Competitive, or Practice vs AI |
View Challenge 4 during the event period | Deal 10,000 Damage as any Mutant in Quick Match, Competitive, or Practice vs AI | Summon 20 Monstro Spawns as Namor in Quick Match, Competitive, or Practice vs AI |
Heal 30,000 Health in Quick Match, Competitive, or Practice vs AI | Read Magneto Lore: The Battle Within | Defeat 10 enemies as Emma Frost in Quick Match, Competitive, or Practice vs AI |
Cerebro Database Namor Mission Rewards

The rewards for the Cerebro Database operate on a line system. This means that players have to complete the missions in a straight line: horizontally, vertically, or diagonally. Completing each line makes you eligible to claim a reward on top. So, you only need to complete seven challenges on the grid in a specific pattern to get all the rewards. However, completing all nine will make the grid disappear and give you access to some bonus lore about the character in question. The rewards for Event 4 are as follows:
- Line 1: 100 Chrono Tokens
- Line 2: Namor X Spray
- Line 3: A Lesser Evil Gallery Card
- Bonus Limited-Time Reward: 75 Units
Players can complete all three lines whenever they wish for as long as the Cerebro Database event is live. However, the bonus limited-time reward can only be claimed within 7 days from the Event’s inception. You don’t need an additional line to claim it; making the third line will automatically grant you this reward.
If you have completed all four event sets, you can claim Mantis’ Flora Maiden costume from the Event section under the Season tab.
