Sonic Mania is an upcoming game in the Sonic the Hedgehog series first unveiled during Sonic's 25th Anniversary party on July 22nd, 2016 at Comic-Con and scheduled to release in 2017, that sees Sonic returning to his 2D roots established on the Genesis and Sega CD, and has the creative input of Christian Whitehead and Headcannon. The game features an enhanced version of the aesthetics of the classic Genesis titles, with polished, better-flowing sprites of the characters. Sonic Mania also introduces a new move called the Drop Dash to replace the decidedly ill-effective Insta-Shield, which the player can charge up in mid-air while pressing the Jump button a second time, sending Sonic dashing forward in a similar fashion to the Spin Dash.
