Flatten The Mountain Progression, Layers and Ending

What the official objective is

The official Roblox description gives the stable goal: mine the mountain flat so sunlight reaches the player again. It confirms the objective but does not publish a layer count, total blocks, finish reward, or save behavior.

Dated mountain structure

The layer-cleared banner is the clearest short-term progress marker in the dated footage. Height shows distance, while the layer count confirms that the current horizontal section has actually been removed.

How to progress through the mountain

1. Clear connected surfaces

Remove one broad section at a time. Scattered holes make the remaining blocks harder to find and can delay the layer-cleared message.

2. Keep automation active

Use Drones and Turrets to work on ordinary blocks while you aim at high-value ore or awkward edges. See the Skill Tree guide for the dated opening order.

3. Watch both Height and the layer message

Height alone may not reveal a small remaining block. Treat a new layer-cleared banner as confirmation that the previous section is complete.

4. Check newly exposed interior space

Buried chests appear inside the mountain in dated public material. Scan each fresh surface before dropping to the next layer.

5. React to the eagle warning

Move outside the red warning area or flight path when EAGLE INCOMING! appears. An interruption is better than losing more time to a hit.

Stuck near the bottom or missing the last block

A September 2 illustrated run documented blocks near the bottom that could appear invisible or glitched while still producing a target outline.

Try this sequence:

1. Rotate the camera slowly across the unfinished surface.
2. Look for the outline or targeting highlight of a tile that does not render normally.
3. Aim at the outlined position and continue mining.
4. Watch the layer counter for confirmation.
5. Do not assume the entire run is broken until every outlined tile has been checked.

This is a dated visual workaround, not proof that every current server has the same rendering issue.

What happens when the mountain is flattened

The documented run ended with a MOUNTAIN FLATTENED! screen that displayed:

• completion time;
• blocks mined;
• Gems earned;
• Cash earned.

The source recorded 400 Gems on a first clear and 500 Gems on a later Storm Hammer run. Because the runs differed in gear and possibly other conditions, the page does not claim a fixed completion reward.

Historical run examples

These are two run records from one September 2 guide, not a controlled experiment. The later run used a stronger pickaxe and an established upgrade economy, so the time difference cannot be attributed to one item alone.

Use the Calculator for your own current Height/min and time-to-target estimate.

Leaderboards

Dated lobby material shows Fastest Times split into four team-size boards:

The September 2 guide reported that its 33:24 solo run placed ninth at that moment. Leaderboard positions can change continuously, so this is historical context, not a current target or ranking claim.

Does progress save?

The public evidence used here does not establish a reliable rule for:

• leaving and rejoining;
• changing servers;
• private versus public sessions;
• Cash persistence;
• Skill Tree persistence;
• mountain-state persistence;
• shared co-op contribution.

Dated material described Gems as the lobby currency carried between runs, but that is not enough to publish a complete cross-server save contract.
