Abandoned Research Facility

The Abandoned Research Facility is the third level of Sonic Boom: Rise of Lyric. It is a hidden research facility infused with ancient ruins that has been deserted for a long time.

Overview
The Abandoned Research Facility is split into two sections: the exterior and interior of the facility itself. The exterior is a distant mountainous archipelago of islands where towering trees and grass grow on top of the rocky cliffs. Ancient rocky structures resembling watchtowers can also be seen on each island.

The interior of the Abandoned Research Facility is a large inactive industrial factory built with ancient ruins. As it has seemingly being abandoned for a long time, weed, moss and other plants have begun growing into the factory (much like the plants at Lyric's Tomb). The factory also appears to have been slightly flooded. At the core of the facility lies a room of four fuse boards that can power a time travelling machine.

Gameplay
This level begins with a speed section in the exterior. After that, the player moves into the facility itself where he/she are greeted to their first tiles puzzle: the player must find the white glowing square tile which when touched will reveal subsequent white tiles and after enough have been touched, the player will be able to progress. The player enters a room where Knuckles and Amy's unique abilities will be required.

Later into the level when Sonic and Tails are separated from Knuckles and Amy, Knuckles and Amy will have to defeat enemies and utilize the EnerBeam and Buttons to solve more puzzles to progress through the level. After a certain point, the player controls Sonic and Tails and are soon introduced to the Hydro Dash, allowing them to scale across the water's surface at high speeds. When Team Sonic reunite together, the player will need to activate the four fuse boards with Knuckles and Amy using the EnerBeam (after clearing out enemies in the area if there are any).

After this, the player will have to fight Shadow the Hedgehog who serves as the boss of this level as Sonic and Tails. After defeating him, the player directly moves onto Lyric's Weapon Facility.
