Radical Highway (Sonic Generations)

Radical Highway is a stage in the 3DS version of Sonic Generations. It represents Sonic Adventure 2 in the Adventure Era. The music of the stage is a remix of Vengeance is Mine.

Act 1
In Act 1, Classic Sonic will have to roll under barrels, bounce over G.U.N. Beetles, swing through bars as well as having to catch the "Got Ring?" blimp in time. There's also G.U.N. planes chasing him down, but he can still attack them. The stage has alot of slopes, so Sonic can gain alot of speed by rolling through them.

Act 2
In Act 2, Modern Sonic runs across buildings, grinds on the rails of the bridges, and dodges G.U.N. Planes. The level is designed in a some-what 3D envierment where some routes are in between others, so depending on what Sonic does, he will end up in either the foreground grinding on the bridges, the middleground going through middle of the bridge or going into the background to avoid a platforming section. There's also hidden rockets that Sonic can find if he jumps at the right time which allow him to skip some areas.

Shadow Rival Battle
Shadow the Hedgehog is the rival boss of this stage, faced by Modern Sonic. Shadow has 3 attacks: Chaos Spear, Chaos Control/Boost and the Homing Attack. Every time Sonic gets ahead of him, Shadow will use his Boost to catch up, which is faster than Sonic's boost and as a result it could end in Shadow running over Sonic. If Shadow is ahead of Sonic, he will start throwing him Chaos Spears and if the hedgehogs are really close to each other, Shadow will try to homing attack Sonic. Sonic can hit Shadow with either the boost, the Slide Attack or the Stomp.

Trivia

 * Of all the stages in Sonic Generations, this stage is the only one that Sonic was never playable in the original game. Shadow the Hedgehog ventured through this stage instead.
 * Even though Sonic was never playable in Radical Highway in Sonic Adventure 2 story-wise (he was playable on the multiplayer racing mode), he has been there at least 2 times: During the intro of Sonic Adventure 2 Battle and Mario & Sonic at the Olympic Winter Games (Dream Snowboard Cross).
 * There's a huge blimp in this level that says "got ring?", which is a reference to "Got Milk?", like in the original. It only appears in Act 1, as only Classic Sonic interacts with it.
 * In Modern Radical Highway, there's some posters that say "Chao Soda" "Pizza! Sonic 20 anniversary" and "Time Eater"
 * This is one of the 2 city levels in the 3DS version of Sonic Generations. The other being Casino Night.
 * Unlike City Escape, this level features Gold Beetles, and there are in fact more than 1 (as seen in a mission) but in this game, they disappear almost immediately after coming on-screen. Sonic needs to quickly homing attack them to reach a higher route.
 * The remix for Act 1 was made by Cash Cash while the remix for Act 2 was made by Circuit Freq.
 * Despite it clearly indicates that you have to boost through the level, it's possible to complete the Special Trial mission for Modern Sonic without using the boost.
 * This is the only level where Classic Sonic can go into the background and foreground.
