Sonic Runners Adventure
Green Hill is a blue-skied lake area with numerous blocky islands dotting the water and a massively wide waterfall up front. These islands' soil are covered in checkerboard patterns in different shades of brown, and on top of them are green-striped grass and the occasional palm tree or two. In the background are also block-based brown mountains with waterfalls running down them. Along the playable path are also all kinds of flowers.
Having received a transmission from Tails who told him to come to South Island, where Dr. Eggman was up to his old tricks again by kidnapping Animals, Sonic arrived in Green Hill to find Tails. Following the eyewitness accounts of local Flickies and clues left behind by Eggman and his robots, Sonic located a Badnik-producing facility and shut it down before finding Tails. There, the fox cub revealed that a bright flash knocked him out during his scroll on the island, and when he woke up, he was in Eggman's clutches and forced to built the doctor a robot teleporter. Sonic tracked Eggman down afterward and defeated him in battle. However, Eggman managed to escape through his damaged robot teleporter in the aftermath, forcing Sonic and Tails to follow him through said device.
Like other levels in Sonic Runners Adventure, levels in Green Hill 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 Speed Type characters.
