Sonic Boom: Rise of Lyrics and Sonic Boom: Shattered Crystal E3 2014 Videos and Screens

Each version is a new chapter in the Sonic Boom universe and will each have their own unique immersive storylines
Serving as a prequel to the stories revealed in the TV series, both Sonic Boom video games are developed by Los Angeles-based Big Red Button Entertainment (Wii U) and Sanzaru Games (Nintendo 3DS) in collaboration with Sonic Team. In these games, Sonic and friends - Tails, Knuckles, Amy, and the newest member of the team, Sticks - will work together as they face their most powerful enemy yet. Lyric is a giant and monstrous snake-like creature from an ancient race. An extremely tech-savvy mastermind who uses a sophisticated robotic body of armour to carry out his own nefarious deeds, he is a formidable enemy and a force to be reckoned with.
With a strong emphasis on collaboration, the roles of Tails, Knuckles, Amy, and Sticks, will be elevated in gameplay that capitalizes on each character's unique talents and abilities. The goal is to prevent Lyric from powering his army of robots and carrying out his plan to destroy the world. The stakes have never been higher, and the only chance to overcome Lyric is to band together and work as a team.
