Drill Baby Drill

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.

Description
The second and final section of the act is full of wooden containers that can be broken particularly by the Stomp, then the Slide and the Sonic Boost. The Spin Jump is not recommended here, as it is slow on breaking them, and wastes time by the fact that it had the player bounces up from every wooden container broken by it.

The act while takes place in the section after running on the building in the major part of it, it is completely new by what it provides in general. As the most of the act is in 2D perspective, and inside the building, and has blocks of wooden containers closing it, leading to the downward, where the Goal Ring is. Among the containers, are bombs, and Cop Speeders policing on unbreakable platforms splitting the finished sections from the unfinished ones. There also blue types of the Time Bonuses and a yellow one, and Spike Traps in which some slides horizontally to block the player way, and some are built upon large unbreakable vertical platforms. Furthermore, there are Super Rings in this act too.

Overview
The act starts like in the Act 2 of Speed Highway, Sonic prepares his gloves and gives a thumb up, then the texts "Ready" and "Go!" appear afterward. The first section is also the same as the said stage, the player has to Sonic Boost on the building until he reaches the second section, but without the Cop Speeders pursuing them.

The second act is as mentioned above, displayed in 2D perspective, and full of wooden containers that the player has to shove through them downward by the Stomp. After reaching the only Point Marker, the act becomes more tricky, with the sliding Spike Traps and more bombs. The end of this section, is the Goal Ring.

Trivia

 * The running on the building part (PC version), is displayed at sixty FPS in this act, unlike in the original stage in the game where it usually drops down to forty FPS or a little more.
 * The set of Springs that appear on each side near the end of the act, launches the player in his spinning animation, but without the aura, unlike Sonic's animation on the other Springs of the game.
