Lava Mountain is the seventh world of Sonic Lost World, which is where Dr. Eggman has built his fortress and the Extractor. As this is the final world in the game, Sonic faces off against each member of the Deadly Six for the last time.


Zone 1

Zone 1 is nothing but a gauntlet on a single rocky planetoid that's constantly being bombarded by volcanic rocks. Zazz, Zomom and Master Zik will land on the planetoid one at a time to get their revenge on Sonic, and once all three are defeated, the Zone is cleared. Each time Sonic defeats a Zeti, the planetoid crumbles, revealing instant death lava pits and giving the hedgehog less room to stand on.

Zone 2

The underwater pipe from Tropical Coast Zone 3 returns, and this time things are far more treacherous, as there are now minecarts filled with bombs that will instantly kill Sonic if he touches them; not even Super Sonic is immune to them. There are plenty of short rails throughout the Zone, requiring a series of quick, well-timed jumps to avoid an ever-increasing number of endless falls. The player also has to avoid colliding with moving walls, as that also constitutes instant death.

Zone 3

Zone 3 is, without a doubt, one of the longest Zones in the game. Sonic must go through three tiers, with the remaining Zeti: Zeena, Zor and Zavok waiting at the end of each one. Each tier has a 3D section set outdoors with lava pits, Badniks and cannonballs, followed by a 2.5D climb up a mechanical tower with conveyor belts, giant gears and lethal lava that will rise after Sonic. This Zone also has the only use of the Green Hover Color Power in the whole game.

Zone 4

The final Zone in the game is a straight-up running battle against Dr. Eggman in his superpowered Eggrobo mech, fought similarly to the Nega-Wisp Armor from Sonic Colors. Super Sonic cannot be used in this Zone.


Things heat up in Lava Mountain as Sonic must avoid deadly fire pits, navigate the inside of volcanoes and escape the path of massive cannons.
