Drill Baby Drill is the fourth Challenge Act of Speed Highway Act 2 in the console/PC version of Sonic Generations. It is unlocked after clearing every Stage in the Dreamcast era and is playable only as Modern Sonic.


This Act takes place within a highly modified section of Speed Highway Act 2, filled with crates, mines, and enemies.


The Act stretches from when Sonic starts running down the side of the building in Speed Highway Act 2 to the lobby at the bottom of the building. Unlike in the main Act, however, upon entering the building with the lobby while running down the side, the gameplay switches to a 2.5D perspective and leads the player across several platforms rather than going straight downward.

The second and final section of this Act is full of wooden containers that block the path. In this Act, they are destroyed most efficiently with the Stomp, Slide and Boost. Among the containers are bombs, and there are Cop Speeders on the platforms. Some surfaces are also covered in spikes, while other spikes float around horizontally. Additionally, there are certain power-ups placed throughout the Act, such as different Time Bonuses and Super Rings.

Upon reaching the lobby at the bottom, the player will find the Goal Ring.


  • When running down the side of the building on the PC version, the game is displayed at sixty frames per second, unlike in the main Act where the framerate usually drops down to forty frames per second or slightly above.
  • The Springs that appear on the walls near the end of this Act launch Sonic without triggering his aura, unlike the other Springs in the game.
