FAQ

Leucism questions

Is Ecos: La Brea free?

Yes. The official Free to Play video says the experience became free to play on Roblox on November 22, 2025. Open the Ecos Team game page and press play. Older pages that still say the game costs Robux describe an earlier access period.

Which animals can I play right now?

The Roblox game description names Dire Wolf, Saber-tooth Cat, Ancient Bison, Western Horse, and Columbian Mammoth. Horse and Dire Wolf are the animals used in the published unlock steps for the others. Smilodon, Ancient Bison, and Columbian Mammoth have their own badges. Orcutt's Coyote and Harington's Pony were announced on June 29, 2026 as upcoming playables after the emotes update. October 2026 community clips describe them on testing servers, and a public unlock quest for them was not documented.

Are there working codes?

No code string was confirmed as active for October 2026, and a code-entry button was not confirmed in the game. Tracks, the coat currency, are earned by missions, Instincts, survival, and territory or migration play. Do not enter passwords or payment details into any box that claims to be a code field.

How do I unlock the Saber-tooth Cat, Ancient Bison, and Mammoth?

The Saber-tooth Cat badge is earned by hunting and killing a Peccary. The Ancient Bison badge is earned by marking a predator, which the animal guide describes doing as a Western Horse. The Columbian Mammoth badge is earned by completing the mammoth quest: interact with a mammoth skeleton so fossil zones appear, then collect the fossils in those zones. Video pin lists are examples, because players report the marked spots are not one permanent map.

What are Tracks?

Tracks are the currency used to buy animal coats. The published shop ladder is Default free, Tier 1 at 300, Tier 2 at 500, Tier 3 at 1000, and Tier 4 at 3000. Some mutation coats are listed at other prices, including 395. Repeating carnivore and herbivore missions have about a one-hour cooldown. Territory, migration, and the separate daily Instinct board do not use that same hour lock.
