River Rush is a sub-level in Sonic Boom: Rise of Lyric. Essentially a straight water route, River Rush takes place on a river leading from the banks of Cliff's Excavation Site to the outer boundaries of the Pit. For this level, the player controls the Riptide.

Using Salty's Riptide, Team Sonic traveled down River Rush to reach the Pit. Along the way, they were attacked by Dr. Eggman until they escaped him.


River Rush takes place on a fairly wide river with tall river backs that winds through the landscape. At the beginning, the river goes through a deep canyon in an orange rock region with a few sand banks and flora. Shortly after the beginning, the player enters a tunnel-like cavern with statues and structures from the Ancients. On the other side of the cave's exit, the landscape changes into a lush forest with thickets of grass and tall tress. At the end of the level, there is also a waterfall.


After fixing the Riptide, Team Sonic got permission from its owner Salty to use it to sail down River Rush to the Pit and the next Chaos Crystal. On the way however, the team was attack by Dr. Eggman, who had formed an uneasy partnership with Lyric and was helping Lyric reclaim the map Team Sonic had taken. While Team Sonic escaped Eggman when their boat fell down a waterfall, Eggman thought they had died and that the map was lost, and left to report back to Lyric.


In River Rush, the player travels down the notorious water stream through the landscape. For this level, the player takes control of the Riptide, which is controlled by all four playable characters.

During the course of River Rush, the player will encounter several barriers blocking the path. To proceed, the player has to clear out the enemies that appear in those locations to lower the barriers. However, the player is not able to backtrack the course. Hazardous environmental obstacles in this level include rocks that cause damage when touched, floating mines that explode upon contact and Eggman himself who fires indestructible cannonballs in random lines from his Eggmobile.

To destroy obstacles and enemies, the player can use either Sonic's fast, but weak Water Cannon, Amy's Ice Cannon for immobilizing enemies, or Tails' powerful, but slow Mortar Shot.


In River Rush, the player's objective is to reach the end of the river. In the beginning, the player first has to clear out the rocks blocking the path. Shortly afterwards, Swarmer Hives will appear to spawn Swarmers which must be destroyed to proceed. The player will then move into a cave while pursued by Swarmer Hives, where they have to clear out the local Swarmer Hives to move on.

Upon exiting the cave, the player enters a new section where they have to clear out Swarmer Hives while dodging mines and Eggman's artillery to continue. The player then has to complete three more sections with similar obstacles, but with increasing number of Swarmer Hives. Eventually, the player arrives at the waterfall where Eggman will shoot at the Riptide. Dodge the shots until the Riptide goes over the waterfall to complete the level. The player will then automatically be taken to the Pit.
