Sonic Runners Adventure
Lava Mountain is a volcanic area with a dark red sky. Covering the horizon in the background are numerous baren mountains, many of which are active volcanos. In front of these mountains is a massive lava lake with islands made of hexagon-shaped rocks in it. On some of these islands are even a few miniature volcanos. The main playable path also has a few half-molten rocks and plant sprouts along it.
Arriving at Lava Mountain with Knuckles during their hunt for Dr. Eggman, Sonic and Tails find the environment too hostile for their taste. Not being bothered by Lava Mountain in the least, Knuckles decides to take the lead. Eventually spotting an Eggman facility in the distance, Knuckles decides to head there, saving a village from Badniks along the way. Arriving at the facility, Knuckles has Tails do some recon. When Tails reports back that the facility is, in fact, a massive Extractor, Knuckles shuts down its core, during which he defeats Eggman as the doctor tries to stop him. However, Team Sonic is left to chase after Eggman again when the doctor makes another retreat.
Like other levels in Sonic Runners Adventure, levels in Lava Mountain have the playable characters running down a path ridden with obstacles, gimmicks and enemies non-stop, and it is the player's job to keep themselves alive until they reach the goal. Along the way, the player can complete certain mission objectives (a few of which are needed to complete the level). The stage is ideal for Power Type characters.
