Dead Line

Dead Line is the final two-act zone in the game Sonic Rush. It appears to be a space station built by Doctor Eggman. Like previous stations, such as the Death Egg, Dead Line is built in the shape of Eggman.

This stage has a new gimmick: Gravity change. At certain points, the gravity will change and the ceiling will become the floor, causing Sonic or Blaze to run at the top of either screens. The stage also features things like cannons, maneuverable rockets, and vacuums that suck up your rings if you get damaged near them. The song for Dead Line is "What U Need".

After the two Acts, the player fights the boss. The only difference is the boss is neither Eggman nor Eggman Nega, instead, the boss is Blaze (or Sonic when playing as Blaze) and Eggman or Eggman Nega will watch in the background. Sonic and Blaze, as bosses, will do new moves that aren't available in-game, like Blaze making pillars of fire, and Sonic doing what looks like Sonic Wind.

After 7 hits, you and your opponent will dash at each other, and the player must rapidly press the A and B buttons to win, knocking Blaze (or Sonic) off the platform.

After finishing this stage as Blaze, she becomes friends with Sonic but quickly discovers Cream was taken by Eggman during the battle and heads to the Unknown (also known as Point-W) to fight him and save Cream. In Sonic's story, he asks Blaze if she's okay and the two become fast friends after Sonic teaches her to open up and to not be so hard on herself. Sonic then rushes off to the Unknown (also known as F-Zone) in his story to fight Eggman Nega. The purple Chaos Emerald and Sol Emerald are found here.

''To finish the boss fight much more quickly, (since your opponent jumps to counter your attack) jump when you get close, and in no time you'll reach the dash section. For this part, it's easier to play this section as Sonic due to his great speed.''
