What Is the Mars Leaderboard Event?
The Mars Leaderboard Event is a competitive Zombies challenge tied directly to Mars Survival, a new endless-round mode introduced at the start of Season 2. Instead of tracking eliminations, score, or time survived, this event ranks players purely by the highest round reached during the event window.
Each player is placed into a leaderboard with 29 other random participants, and your final placement determines which rewards you earn once the event concludes.
How the Mars Leaderboard Ranking Works
Unlike traditional Zombies challenges, this event is straightforward—but unforgiving.
Key Rules
-
Rankings are based only on highest round achieved
-
Higher rounds = better leaderboard placement
-
One leaderboard group of 30 players per participant
-
Rewards are distributed after the event ends
If two players reach different rounds, the higher round always wins placement—no tiebreakers like kills or time survived.
Two Types of Rewards You Can Earn
The Mars Leaderboard Event offers two separate reward tracks:
-
Leaderboard Placement Rewards – Earned based on your final ranking
-
Challenge Rewards – Earned instantly by surviving specific rounds
You can earn all challenge rewards regardless of leaderboard position, making them accessible even if you don’t compete for top spots.
All Mars Leaderboard Placement Rewards
These rewards are granted only after the event ends, based on where you place on your leaderboard.
Top 30 Placement
-
Bird Brain – Emblem
-
Exit Strategy – GobbleGum
This tier is effectively a participation reward. As long as you log a run, you’ll walk away with these items.
Top 15 Placement

Planet Flamingo – Weapon Camo
-
Flavor Hex – GobbleGum
This is where cosmetic rewards start to stand out, especially for camo collectors.
Top 10 Placement
-
Idle Eyes – GobbleGum
-
Armor Gettin’ – GobbleGum
Both GobbleGums are highly valuable in high-round Zombies play, making this tier especially appealing.

-
Gift Card – GobbleGum
The Mars camo is one of the most sought-after cosmetics in the event, tied to strong leaderboard performance.
1st Place Only
-
Hidden Power – GobbleGum
This exclusive GobbleGum is reserved for the top-ranked player in each leaderboard group, making it one of the rarest rewards available during Season 2.
All Mars Survival Challenge Rewards
Challenge rewards are unlocked immediately upon reaching specific rounds in Mars Survival. These rewards do not depend on leaderboard placement.
Survive 10 Rounds
-
Die Pitched – GobbleGum
A simple reward that most players will earn quickly.
Survive 25 Rounds
-
Ornamental – Weapon Charm
A cosmetic reward that shows off your Mars Survival progress.
Survive 50 Rounds
-
Elemental Exposure – GobbleGum
This is a major milestone reward and often the stopping point for many solo players.
Survive 100 Rounds
-
Feathered Idol – Kogot-7 Weapon Blueprint
The ultimate challenge reward. Reaching Round 100 in Mars Survival is no small feat and proves true Zombies mastery.
Event Dates and Deadline
Timing is critical, as this event is extremely limited.
Mars Leaderboard Event Schedule
-
Start: February 5 at 9:00 AM PT
-
End: February 9 at 10:00 AM PT
Once the event ends:
-
Leaderboard placement rewards are distributed

There will be no second chance to earn these cosmetics and GobbleGums.
Tips for Climbing the Leaderboard
-
Prioritize survival over speed—round count is everything
-
Use GobbleGums strategically in later rounds
-
Play during off-peak hours to avoid competitive leaderboards
-
Secure a strong early run to discourage others from overtaking you
Even a small round advantage can mean the difference between Top 10 and missing out entirely.
