Exciting news for Marvel Rivals players: a brand-new event, Galacta’s Cosmic Adventure, is set to launch this Friday, March 7, 2025, and will run until April 11, 2025. This limited-time event introduces fresh gameplay mechanics, a brand-new mode, and a variety of free rewards for players to unlock.

The event comes alongside the highly anticipated Clone Rumble mode, as well as a special board-game-style event mechanic where players can earn rewards by rolling dice. One of the biggest highlights is the new Mrs. Barnes Black Widow skin, which players can obtain by participating in event missions.
Clone Rumble: Embrace the Chaos
At the heart of this event is Clone Rumble, an experimental game mode that shakes up the standard Marvel Rivals format. Instead of traditional hero selection, all players in the match vote between two randomly chosen heroes at the start of the game. Once the voting is complete, players must pick one of the two chosen characters, resulting in teams composed entirely of identical heroes.

This unique twist opens the door for some truly chaotic matchups, where six identical heroes face off against another team of six identical heroes. Imagine an entire battlefield filled with only Human Torches, raining fire across the map, or a match where everyone is playing Magneto, filling the screen with metal debris.
How Clone Rumble Works:
- 6v6 battles where every player selects between only two pre-voted heroes.
- Matches take place on the Intergalactic Empire of Wakanda: Birnin T'Challa, a special event-exclusive map.
- Players must work with their team of identical heroes to complete mission objectives and win the match.
- Traditional team compositions and strategies are thrown out the window, forcing players to adapt to unique, mirrored hero matchups.
This game mode is a refreshing change from the usual competitive and quick match modes, offering something unpredictable and wildly entertaining.
Galacta’s Cosmic Adventure: A Board Game-Style Event
Alongside Clone Rumble, the Galacta’s Cosmic Adventure event features a unique activity board system where players roll dice to move across different spaces, unlocking rewards based on where they land.
How The Event Works:
- Players earn event tokens by completing daily and weekly missions.
- These tokens can be exchanged for dice rolls, which determine where players move on the Cosmic Adventure board.
- Landing on different spaces grants various rewards, including cosmetics, in-game currency, and other exclusive event items.
- The board layout, token economy, and specific rewards are expected to change as the event progresses.
This event structure encourages daily participation, as players must keep earning tokens and rolling dice to maximize their rewards before April 11.

Free Rewards: The Black Widow Mrs. Barnes Costume & More
One of the most exciting aspects of the Galacta’s Cosmic Adventure event is the free rewards that players can earn simply by playing. The biggest highlight is the Mrs. Barnes skin for Black Widow, which gives Natasha Romanoff a sleek, tactical look inspired by a universe where she takes on the Winter Soldier persona.
How To Unlock The Mrs. Barnes Black Widow Skin:
- Complete event missions to earn event tokens.
- Use these tokens to roll dice and move across the Cosmic Adventure board.
- Land on the right spaces or accumulate enough event progress to unlock the skin before the event ends.
