The 25 Years of Sonic the Hedgehog

Sonic Boom Shattered Crystal (2014)

The game began immediately after its in-game comic strip prequel, where Amy was in the middle of a fight with Lyric the Last Ancient who wanted the info she has on finding the Lost Crystal of Power. After dealing a blow that stunned him for a bit, Amy contacted Sonic to tell him of her findings, only to be knocked off guard by Lyric, (getting disarmed in the process). Despite her protests, Lyric managed to plant a device on Amy's head, knocking her unconscious as he introduced himself to an outraged Sonic. After destroying Amy's communication device with his tail, Lyric made his getaway.

After completing Seaside Beach, Sonic meets up with Tails, explaining the situation and asking for his help in tracking down Amy. Tails eagerly agreed and revealed his newly-developed form of technology that can allow the viewing of destroyed files. Sonic was glad at the fact, but then wondered how Sticks would react when she learns of Amy's capture. After finding their new friend Sticks the Badger, the duo told her their current predicament, with Sticks nonchalantly running off to find Amy as they give chase. After a race, Sonic urged Sticks to join the team, as teamwork was the only way they can win. Meanwhile, Tails managed to decipher some of Amy's research logs, which prompted them to head for the Scrapyard, where Knuckles last was. The group found Knuckles without much trouble and the echidna was eager to help, claiming that they should get a move on. With the full team assembled, the group headed for Shadow Canyons, where they noticed Shadow the Hedgehog standing off in the distance, only to run off. Wondering what he was up to, the group followed him, and after a race, he came back to his senses and everyone realized that he has been possessed by Lyric the entire time via a mind control device similar to the one used on Amy. After being taunted by a hologram of Lyric that came from the broken device, Shadow skated off in hot rage, with the others agreeing to follow him into the Ancient Ruins.

After completing Ancient City, the group discovered that a large robot facility was hidden beneath the ruins, and was responsible for all of Lyric's robots. They decided to shut it down, and were ambushed by Metal Sonic while down there. Sonic raced him, but loses and Tails shortly managed to track his movements and found that he was headed for the Volcanic Crater. Once there, the team found themselves lost, but decided not to give up. After deciphering another of Amy's logs, they discovered that a hangar of ancient planes was hidden in the volcano and decided to search for it. After finding it, the group headed off, and managed to escape the volcano, though Tails had some trouble steering the plane, and ended up crash-landing on the Cloud Sanctuary, (much to an airsick Knuckles' relief). Meanwhile, it was revealed that Amy had regained consciousness and was adamantly refusing to translate the ancient language for him despite his orders, all the while claiming that Sonic and co. will come for her.

After Sonic, Tails, Knuckles, Sticks, and the freed Amy finally arrived on Lyric's airship, they were being to flaunt the power of teamwork in front of the dastardly snake, only for Lyric to get an idea and trapped everyone but Sonic in the same glass ball that Amy had been imprisoned in previously. Sonic gave chase, and after fighting Lyric, he freed everyone. Their rejoicing was cut short however, as Lyric regained consciousness and prepared a giant robot to finish the group off. Shortly later, Shadow intervened and dismantled the mech, rendering it useless and kicking Lyric out the bomb-doors of his own ship (which Sonic had opened just as this happened). The team rejoiced again, as Sticks gave a slightly incorrect speech about teamwork. The adventure was over, and Shadow walked off, claiming to be a loner and superior to Sonic. Sonic was dismayed over the fact that Shadow did not want to join them, as he thought that he would make great addition to "Team Sonic". Sonic and Knuckles then got into a brief argument over what the team's name should be as the group began the long journey back home.
