Ecos: La Brea puts you in Ice Age Los Angeles about 25,000 years ago, in the ecosystem preserved by the La Brea Tar Pits. You are an animal, not a human survivor. The current public description lets you pack as a Dire Wolf, ambush as a Saber-tooth Cat, lock horns as an Ancient Bison, gallop as a Western Horse, or change the landscape as a Columbian Mammoth.
Before you leave the menu
- Join from the official Roblox page. The game has been free to play since November 22, 2025.
- Start as a Western Horse if you want speed, a map lesson, and the published path to Ancient Bison. Start as a Dire Wolf if you want to hunt and later unlock the Saber-tooth Cat.
- Open the left menu and learn where Instincts, bio stats, group, billboard, settings, map, and your Track count sit.
- Read the keybinds in settings before you trust an older chart. On January 23, 2026, Ecos Team said the mark-player key is Q by default for new players, and herbivore call 2 no longer marks players. Existing players keep their old binds until they change them.
First ten minutes
- As a horse, eat plants and watch the horizon. Edible plants pay a small Track reward on a cooldown, and drinking at a mineral lick is its own mission.
- As a wolf, use scent (B on the published keyboard list) and look for game trails. Flat-headed Peccaries are tied to those trails, and killing one is the Saber-tooth Cat badge.
- Do not stand in tar. A short step can be safe. Staying on tar slows you and then traps you. A trapped animal cannot free itself. Sleeping to respawn kills you and leaves a carcass.
- If you have a survival score you want to keep, leave with the menu return (L on the published list). That starts a 10-second countdown. You cannot menu out while bleeding or in combat.
What to do next
Mark a predator as a Western Horse to work on the Ancient Bison badge. Kill a Peccary as a carnivore for the Saber-tooth Cat. When you can survive a long walk, start the mammoth quest from a mammoth skeleton and follow the fossil zones the quest marks. Coat shopping can wait until you understand which animal you actually play.
What this first session is not
There is no confirmed reward-code box. There is no published growth ladder from baby to elder for these animals. Orcutt's Coyote and Harington's Pony have official fauna pages and were announced as playables in development. Do not hunt for a secret menu entry for them until the game itself shows an unlock.
