MLBB celebrates its 10th anniversary with free skins, special rewards and limited-time events from September 4, followed by Season 42 and eight hero revamps on September 16.

Mobile Legends: Bang Bang is preparing for one of its biggest celebrations of the year as the game officially begins its 10th Anniversary on September 4, 2026, followed less than two weeks later by the arrival of Season 42 on September 16.

The anniversary celebration brings a packed schedule of free rewards, including anniversary-exclusive skins, Epic Skin Chests, special effects, gameplay privileges and commemorative items. Players will also have opportunities to obtain returning rewards from previous anniversaries.

Then, on September 16, MLBB moves into S42, the 10th Anniversary Special Season, bringing eight revamped heroes, a full skill revamp for Masha and a new visual design for Sanctum Island.

Together, the anniversary events and S42 make September a major month for Mobile Legends players.

MLBB 10th Anniversary Officially Begins September 4

The main 10th Anniversary celebration begins on September 4, with several events launching simultaneously.

Rather than limiting the celebration to a single login event, MLBB is spreading its anniversary activities across September, October and into the beginning of November.

Free skins are among the biggest rewards, but players can also earn exclusive anniversary cosmetics, commemorative items and temporary gameplay benefits.

10th Anniversary Celebration Battle Pass

From September 4 to November 1, players can participate in the featured 10th Anniversary Celebration Battle Pass.

By participating in the event, players can obtain several rewards for free, including:

• Nana "Stardust Dreamer" Anniversary-exclusive skin
• Epic Skin Selection Chest
• Random Epic Skin Chest
• Exclusive Spawn Effect
• Exclusive Elimination Effect
• Additional anniversary rewards

Items from MLBB's previous 5th and 7th Anniversary celebrations will also return for a limited time.

The anniversary period will additionally give players opportunities to obtain the brand-new Chou "Starforger's Glory" Special skin and choose between two returning anniversary skins: Miya "Moon Priestess" from the 5th Anniversary and Johnson "Starblazer" from the 7th Anniversary.

A Decade of Legends

Another major event beginning on September 4 is A Decade of Legends.

Running from September 4 to November 1, the event focuses specifically on commemorating ten years of Mobile Legends.

Players who meet the event requirements can earn rewards including:

• Global limited-edition numbered physical MLBB Artbook
• Years of Play Title
• Top-tier Animated Avatar Border
• New Animated Avatar
• Additional anniversary rewards

The numbered physical Artbook stands out as one of the more unusual anniversary rewards, giving eligible players a physical collectible commemorating MLBB's first decade.

Call Back Friends for a Free Special Skin

MLBB is also encouraging players to bring former players back for the anniversary.

From September 4 to October 4, players can participate in a callback event and complete its requirements to obtain a Special skin for free.

The event runs for approximately one month, giving players more time to complete its requirements compared with some of the shorter anniversary activities.

10th Anniversary Battle Privileges

The first few days of the celebration will also feature special gameplay privileges.

From September 4 to September 7, players participating in matches can access:

• All Heroes Free Trial
• 100 Skins Free Trial
• Free Emblem Trial
• Double Star-raising Points ×3
• Double Protection Points ×2

The event gives players four days to experiment with heroes and skins while also benefiting from additional Ranked progression bonuses.

For players still pushing their rank before S42 arrives, the timing makes these bonuses particularly useful.

10th Anniversary Gameplay Challenge

Another longer event begins alongside the anniversary on September 4.

The 10th Anniversary Gameplay Challenge runs from September 4 to October 25.

Players who participate and complete the required objectives can obtain the new 10th Anniversary Interactive Effect: Birthday Fireworks for free.

This event continues well beyond the launch of S42, meaning players will still be able to progress through it after the new Ranked season begins.

Season 42 Arrives September 16

Less than two weeks after the anniversary celebration begins, Mobile Legends will enter its next Ranked season.

Season 42 begins on September 16, 2026.

S42 is being introduced as the 10th Anniversary Special Season, directly connecting the new season with the wider anniversary celebration.

The update will bring several significant changes to familiar parts of the game, with eight heroes receiving revamps and Sanctum Island receiving a new visual design.

For players still working toward their Season 41 Ranked goals, September 16 will mark the transition into the new season.

Eight Heroes Are Being Revamped for S42

One of the biggest features of the Season 42 update is the simultaneous revamp of eight existing heroes.

The lineup includes:

• Masha
• Bruno
• Clint
• Brody
• Paquito
• Badang
• Kadita
• Luo Yi

The selection covers multiple roles, including Fighters, Marksmen and Mages.

Rather than every hero receiving exactly the same type of update, the revamps appear to vary in scope. The S42 update focuses heavily on refreshing the visual presentation of these heroes, while at least one will receive a much larger gameplay overhaul.

Masha Gets a Full Skill Revamp

Among the eight heroes, Masha is receiving one of the most significant changes.

MLBB's S42 preview specifically highlights the Direbear warrior from Northern Vale, confirming a full skill revamp.

That means Masha's update goes beyond a visual refresh and could substantially change the way she functions during matches.

Players who currently use Masha should therefore pay particular attention to the final September 16 patch notes, as her updated skills could affect her builds, rotations and overall playstyle.

Any specific values or mechanics previously seen on the Advance Server should still be treated as testing information until they appear in the final Original Server update.

Bruno, Clint and Brody Represent the Marksmen

Season 42 also refreshes three familiar Marksmen: Bruno, Clint and Brody.

Having three Marksmen included in the same revamp update makes Gold Lane one of the roles most visibly affected by S42.

Bruno has previously appeared in Advance Server testing with visual and gameplay adjustments, although players should wait for the final patch before assuming every test-server mechanic will remain unchanged.

Clint and Brody are also included in the anniversary revamp lineup, giving players more familiar heroes to revisit once S42 launches.

Paquito and Badang Join the S42 Revamps

Paquito and Badang represent another part of the Fighter lineup receiving attention.

Their inclusion alongside Masha gives Fighter players three revamped heroes to explore during the new season.

As with the other heroes, the safest approach is to wait for the final Original Server patch notes before judging how strongly any gameplay changes will affect their positions in the S42 meta.

Kadita and Luo Yi Complete the Lineup

The remaining two heroes are Kadita and Luo Yi.

Their inclusion brings Mage-focused gameplay into the eight-hero revamp lineup and makes the anniversary refresh more diverse across different roles.

With eight heroes changing at the same time, players who regularly use any of them should check their updated hero information after downloading the September 16 patch.

Sanctum Island Gets a Brand-New Visual Design

The S42 refresh isn't limited to heroes.

Sanctum Island is also receiving a new visual design.

As MLBB's primary battlefield, the visual update will affect the environment players see throughout regular matches.

It is important, however, to distinguish a visual redesign from a confirmed gameplay overhaul.

The information currently announced for S42 specifically describes a new visual experience for Sanctum Island. Players should therefore not automatically assume that jungle paths, objectives or other map mechanics are changing unless those adjustments are separately confirmed.

The complete September 16 patch notes should provide a clearer picture of any additional battlefield changes.

Major dates

• September 4 – November 1: 10th Anniversary Celebration Battle Pass
• September 4 – November 1: A Decade of Legends
• September 4 – October 4: Call Back Friends event
• September 4 – September 7: 10th Anniversary Battle Privileges
• September 4 – October 25: 10th Anniversary Gameplay Challenge
• September 16: Season 42 begins
• September 16: Eight revamped heroes arrive
• September 16: Sanctum Island receives its new visual design

This creates a clear progression throughout September.

Players first enter the anniversary celebration and begin collecting free rewards on September 4. Then, less than two weeks later, the gameplay side of the celebration expands with S42, its hero revamps and the refreshed battlefield.

What Could S42 Mean for the Meta?

It is still too early to establish a reliable Season 42 tier list.

Eight heroes are being revamped, but a revamp does not automatically mean every hero will become stronger.

Visual changes alone do not necessarily affect competitive strength, while more substantial skill and balance adjustments can have a much greater impact.

Masha is currently the most important hero to watch because her update has specifically been described as a full skill revamp.

Players should also keep an eye on the other seven heroes once their final Original Server changes are available.

Advance Server testing can offer an early look at possible adjustments, but balance values and mechanics can change before reaching the live server.

More Anniversary and S42 Updates Are Coming

The information revealed so far does not necessarily represent everything planned for MLBB's anniversary period.

Additional S42 details are expected as the September 16 update approaches, particularly regarding the final versions of the eight hero revamps.

Players should therefore distinguish between confirmed Original Server announcements and information currently circulating from Advance Server testing.

The final patch notes will be the most reliable source for exact skill adjustments, balance changes and any additional battlefield updates.

Conclusion

Mobile Legends: Bang Bang is preparing for a packed September as the game celebrates ten years since its launch.

The 10th Anniversary officially begins on September 4, introducing free skins, Epic Skin Chests, anniversary cosmetics, special gameplay privileges, a physical MLBB Artbook opportunity and several limited-time events.

The celebration then leads directly into Season 42 on September 16, which arrives as the 10th Anniversary Special Season.

S42 will bring eight revamped heroes alongside a new visual design for Sanctum Island. Masha will receive one of the biggest changes through a full skill revamp.

With anniversary activities continuing before and after the Ranked reset, the celebration is much larger than a single-day event. September will combine free rewards and commemorative content with one of the game's major seasonal updates as MLBB enters its next decade.
