Tails: Way past Fast is the second Challenge Act of Green Hill Act 2 in the console/PC version of Sonic Generations. It is unlocked after clearing every Stage in the classic era and is playable only as Modern Sonic.
This Challenge Act takes place in Green Hill Act 2. The first section is a new exclusive area while the second is a modified version of the normal Stage. The Challenge Act includes more elements than the regular Stage, such as new wooden platforms and many more Buzz Bombers and Crabmeats.
In the beginning, the player must climb some wooden stairs to a Spring and use it to get to higher ground. They then have to cross a gap - either along the ground, over bridges or by Homing Attacking a Buzz Bomber to another Spring which takes them to a Grind Rail. After getting on the Grind Rail, the player will have to Homing Attack over a gap using Buzz Bombers. After the Grind Rail, the players have to reach another Spring, either by using the Homing Attack on some Buzz Bombers and going through a Dash Ring, or moving along the ground. This Spring will take the players to the original section of Green Hill.
After continuing down this path while crossing barriers, the player can either continue through a Shuttle loop or break through a wooden bridge with the Stomp and continue on the path below. The player will be flung to the last stretch with barriers at the end, where they can either move along the ground or take shortcuts using the Buzz Bombers, Dash Rings and Rainbow Rings to reach the Goal Ring
- When the player gets near/hit by a Crabmeat near the wooden bridge, the camera will glitch and continue zooming in/out the scene.
- When completing the Challenge Act, Tails will say that he is not surprised that Sonic is faster than him when talking to him in White Space.
- The title may be a reference to Sonic's catchphrase "Way Past Cool" from the Sonic the Hedgehog television series and Sonic Underground.
