4k. MOUNTAIN PASS

Activate Keira's Machine: Ensure you have at least 45 Power Cells (maximum 66 at this point). Use the pontoon bridge to reach Keira and speak with her.

Defeat Klaww: Circle around to the front of the levitation machine and climb up. Enter the canyon to face Klaww.

Phase 1: Hop between three floating stone slabs in the lava. Dodge Klaww's boulders. After Klaww recedes, collect the Blue Eco to power a bridge. Dodge more boulders on the bridge and collect Yellow Eco at the end. Blast Klaww with Yellow Eco until he drops his boulder on himself. Quickly return to the starting platforms before Klaww's boulder lands.

Phase 2: Klaww resumes shooting boulders, which are slightly faster. Dodge them and collect Blue Eco to create the bridge again. This time, the bridge has missing pieces, so cross carefully. Collect Yellow Eco and blast Klaww again, then flee back to the platforms from his boulder.

Phase 3: Klaww's boulders are even faster. Collect Blue Eco to create the bridge, which has even more missing pieces. Blast Klaww with Yellow Eco for the final time to defeat him and earn a Power Cell.

Continue: Use the newly appeared platforms to reach the far shore and continue through the Mountain Pass.

Reach the End of the Mountain Pass: Race through the pass, avoiding pits, Dark Eco crates, and explosives. You must reach the end before the flying Lurkers do, as you cannot defeat them. Use speed boosts and carefully control your Zoomer, especially in the cave area with giant explosive barrels that cause instant death.

Find the Hidden Power Cell: This requires completing the "Find the Yellow Vent Switch" challenge in Snowy Mountain first. Return to the Mountain Pass (near Rock Village is best). Drive the Zoomer until the big jump. Look for a Yellow Eco vent. Charge up, then blast the boulder behind the vent. Speed into the secret passage, leap the gap, and collect the Power Cell.

Free 7 Scout Flies: It's recommended to collect these after completing the level once.

One is at the base of a hill early in the Pass.

The next is on the ground where the path reconnects.

The third is in plain view before a narrow path over a pit.

After the huge jump, one is slightly to the right of four wooden chests.

One is on the path through the cave.

Another is in the same cave, to the right of a stalagmite/stalactite.

The last one is among explosive barrels before the detonator. Destroy the detonator first, then retrieve the Scout Fly.

Find Missing Precursor Orbs: Most Precursor Orbs are in the open. Replay the level to find any missed airborne orbs or smashed metal boxes.
