-----------------------------------------------------------------------

Mission 1: "Make the S rank!"
Unlocked: From start
Character: Choice
Upgrades Applied: None
On Radio: Gary; Prof. Oak (only if playing as Gary)
Mission: Get enough points in this stage to attain at least an S rank.
Detail: In this mission, your goal is to make it through the regular mission while scoring enough points to attain a high rank. In this mission, you get points for destroying enemies and also for completing objectives. (Note that defeating enemies is optional in this stage, since there are no GUN Soldiers in this stage and no objectives that call for defeating enemies.) Points are displayed where you'd normally find the clock in a timed objective. At the end of the stage, the points you got during the mission, as well as bonus points based on time taken and remaining health, are added up and you'll be given your ranking. If that ranking is at least S, you clear the mission.
Challenge Mode: You're given the Jenny Mode time limit of 15:45 to complete the mission. Use the Select button to switch the time display with the points display and vice versa.

Mission 2: "Flying enemy ring trial!"
Unlocked: Clear Mission 1
Character: Duplica
Upgrades Applied: None
On Radio: Prof. Oak
Mission: Use flying enemies to pass through 45 trick rings.
Detail: Odds are you'd have at least one mission where you'd have to use Duplica's robot-jacking skills, right? Here, there are 45 special trick rings placed through the air, and the only way you can get through them without falling to your death is by jacking various flying enemies and flying them through the trick rings. You begin the stage aboard a Spiked Purple Bat, but you can also use other Spiked Purple Bats, Plane Birds, and other flying enemies as well. (For the record, these enemies are normally in this stage, but were never mentioned in the walkthrough.) You don't have to stay in a flying enemy at all times. If the robot's health getting is low, you can always dismount and try jacking another robot. The mission may take awhile, and locating all 45 of the trick rings can be tough, but once you've found and flown through all 45 trick rings, you clear the mission. Not all of the rings are up high--at least one of them is only a few inches above the lowest reachable point on the stage before oblivion. There is one way to fail the mission besides being defeated, and that's if all the reachable flying enemies are destroyed before you reach quota. And, of course, there are a few that can't be reached due to alterations on the course sealing off the paths that lead to them.
Challenge Mode: The flying enemy quota is reduced to 80% of normal, and there are 65 trick rings instead of 45.

Mission 3: "Destroy 30 Eggman robots!"
Unlocked: Clear Mission 1 with silver-star rank, Clear Mission 2
Character: Brock
Upgrades Applied: None
On Radio: Gary
Mission: Destroy 30 of Dr. Eggman's robots.
Detail: In this mission, your goal is to destroy all 30 of Dr. Eggman's robots that appear in this stage for this mission. Only those that appear on Route 99 will appear here. If you manage to destroy them all before reaching the GUN Highway, you clear the mission. You'll have to try again if you reach the GUN Highway.
Challenge Mode: The quota is 60 of Eggman's robots.

Mission 4: "What if there was no bomb near the off-ramp?"
Unlocked: Clear Mission 1 with gold-star rank, Clear Mission 3
Character: Eusine
Upgrades Applied: None
On Radio: Cloud
Mission: Defeat Luka.
Detail: For this mission, your goal is to get to where you'd normally fight Luka and then defeat her. You need not worry about the normal objectives, just focus on getting to the where Luka is. The cutscene will play, followed by the fight. Your goal is to defeat Luka. If you can defeat Luka before Luka defeats you, you've cleared the mission.
Challenge Mode: A time limit of 15:45 for the whole stage is in place.

Special Mission: "Which robots do not belong here?"
Unlocked: From start
Game Pak: Sonic Advance 3 (GBA)
Character: Drake-HE4
Upgrades Applied: None
On Radio: Steven
Mission: Find all 30 GUN Hunter robots without hurting humans.
Detail: This mission has you looking for robots that you normally wouldn't find on this stage. Since this stage is normally inhabited by Dr. Eggman's creations, with GUN's presence only in imagery, it's no surprise that the robots you're looking for are the most abundant GUN Troops in the game: GUN Hunter robots. To clear this mission, you need to find all 30 of the robots. Defeating them isn't necessary, as simply seeing them counts the counter up; however, defeating them is not harmful to your mission. There are also 5 GUN Soldiers present in this mission also looking for the GUN Hunters. They will not attack you here, as they're here for the same reason you are, you do damage to any of them, you fail the mission. Once you've caught all 30 GUN Hunters in your vision, you clear the mission.
Challenge Mode: A time limit of 12:00 is in place.

Mission 1: "Make the S rank!"
Unlocked: From start
Character: Choice
Upgrades Applied: None
On Radio: Gary; Prof. Oak (only if playing as Gary)
Mission: Get enough points in this stage to attain at least an S rank.
Detail: In this mission, your goal is to make it through the regular mission while scoring enough points to attain a high rank. In this mission, you get points for destroying enemies and also for completing objectives. (Note that episode 4 in the story mode reverses the mandatory status of robots and humans, hence it's also reversed for the episode 4 stages in this mode. Here, it's mandatory to destroy the robots but optional to defeat the humans, especially since only robots can drop Chaos Drives; other episodes tend to have humans mandatory and robots optional.) Points are displayed where you'd normally find the clock in a timed objective. At the end of the stage, the points you got during the mission, as well as bonus points based on time taken and remaining health, are added up and you'll be given your ranking. If that ranking is at least S, you clear the mission.
Challenge Mode: You're given the Jenny Mode time limit of 10:15 to complete the mission. Use the Select button to switch the time display with the points display and vice versa.

Mission 2: "Motorcycle race! Beat the admins to the falls!"
Unlocked: Clear Mission 1
Character: Tyson-HL
Upgrades Applied: None (not that they'd matter anyway)
On Radio: Morrison
Mission: Ride the motorcycle and beat Courtney and Seth to Metal Rapids.
Detail: In this mission, you're riding a Motorcycle on the GUN Highway. Your goal is to win a race against two team admins of equal standing within their teams, Team Magma's Courtney and Team Flora's Seth, who are both also riding Motorcycles. You can't dismount your Motorcycle here. The challenge is quite tough, since all three Motorcycles have the same stat bases, so it may take a few tries to come out on top. Thankfully, there are no enemies present in this stage, not even one of the stage's usual GUN Hunter robots. The stage also has some tweaks in the forms of ramps and boost pads that increase your speed temporarily if used right. If either Courtney or Seth reach Metal Rapids before you do, you fail the mission. If you reach Metal Rapids before Courtney and Seth do, the mission is clear.
Challenge Mode: Courtney and Seth are joined by a third rider--the Go-Rock Squad's Billy. You must now beat three opponents to the falls.

Mission 3: "Destroy 40 GUN Hunters!"
Unlocked: Clear Mission 1 with silver-star rank, Clear Mission 2
Character: Jason
Upgrades Applied: None
On Radio: Steven
Mission: Destroy 40 GUN Hunter robots.
Detail: In this mission, your goal is to destroy all 40 GUN Hunter robots that appear in this stage for this mission. If you manage to defeat that many before reaching Metal Rapids, you clear the mission. You'll have to try again if you reach Metal Rapids.
Challenge Mode: The GUN Hunters increase in strength to be similar to the ones at Metal Rapids.

Mission 4: "Demolition derby! Take out all of the Rhinoes!"
Unlocked: Clear Mission 1 with gold-star rank, Clear Mission 3
Character: Roark
Upgrades Applied: None (not that they'd matter anyway)
On Radio: Cynthia
Mission: Bash all of the harmable GUN Rhinoes using your ATV.
Detail: For this stage, you're riding an ATV given enough X Attack from the get-go to defeat any GUN Rhino--save the ones vulnerable only to Explosion--in one strike. You can't dismount your ATV in this mission, and if the ATV's health hits zero, you fail the mission. There are 50 GUN Rhinoes on the road to Metal Rapids. You need to defeat 40 of them, as there are 10 of each variety of GUN Rhino, including ones which only Explosion can damage, leaving 40 GUN Rhinoes vulnerable for your ATV to defeat. Ram all 40 and you clear the mission.
Challenge Mode: There are now 80 GUN Rhinoes on the road, 16 of each variety, and you must now strike 64 GUN Rhinoes to clear the mission. Additionally, a 10:00 time limit is in place.

Special Mission: "Is this the end of a legend of the Chao world?"
Unlocked: From start
Note: A game pak must be a standalone for it to work. The Sonic Advance/Sonic Pinball Party multicart won't work, and neither will the Europe-only Sonic Advance/Sonic Battle multicart.
Game Pak: Sonic Advance (GBA), Sonic Advance 2 (GBA), or Sonic Pinball Party (GBA)
Character: Jasmine, Wearing Inhibit Belt
Upgrades Applied: Materia
On Radio: Lance
Mission: Protect Chacron for 8:00. Harm no humans.
Detail: This mission has you protecting a single Chao that GUN Troops, mainly Hunter robots as usual, are after. However, you'll understand why protection is needed once you find out that the Chao in question is Chacron, a Chao Race legend (his voice is that you'd hear out of pretty much any Chao out there). Unlike other escort missions, Chacron can be treated like a hold item similar to a Scope, just use X to pick him up. Note that Chacron can still be targeted even while being held, and if Chacron's HP hits zero, you fail the mission, so don't even think of using Chacron as a shield. You have 8 minutes until GUN decides to give up the pursuit. If time runs out, you clear the mission. One more thing, Chacron would never hurt a human, and you must not do so either. There are a few GUN Soldiers not piloting mechs in this stage, and if you do even 1 point of damage to any of them, you fail the mission.
Challenge Mode: The time limit is now 20:00.

Mission 1: "Make the S rank!"
Unlocked: From start
Character: Choice
Upgrades Applied: 8 Red Chaos Drives, 8 Purple Chaos Drives, 8 Green Chaos Drives, 8 Yellow Chaos Drives
On Radio: Gary; Prof. Oak/blackout (only if playing as Gary)
Note: "Blackout" actually refers to the status of having nobody at the other end of the hand radio. In this case, you won't have anyone on the radio here if you're fighting the Commander with Gary.
Mission: Get enough points in this stage to attain at least an S rank.
Detail: In this mission, your goal is to make it through the regular mission while scoring enough points to attain a high rank. In this mission, you get points for destroying enemies and also for completing objectives. (Note that the Commander is a "defeat" objective, he's the only human foe you must actually defeat in episode 4.) Points are displayed where you'd normally find the clock in a timed objective. At the end of the stage, the points you got during the mission, as well as bonus points based on time taken and remaining health, are added up and you'll be given your ranking. If that ranking is at least S, you clear the mission.
Challenge Mode: You're given the Jenny Mode time limit of 20:00 to complete the mission. Use the Select button to switch the time display with the points display and vice versa.

Mission 2: "Don't let Uxie reach the Commander!"
Unlocked: Clear Mission 1
Character: Lucy
Upgrades Applied: Materia
On Radio: Scott
Mission: Stop Uxie's flight to the Commander.
Detail: This mission has you chasing a legendary Pokémon. The Commander is out to capture Uxie, and Uxie is flying right toward him! After you've completed the jet-ski ride, you'll be on foot and in pursuit. GUN Troops, mainly Hunter robots as is usual, do appear here, but you don't need to fight them. Lucy and Uxie both have the same speed to start out with, so you'll need to grab at least one X Speed in order to actually catch Uxie. Thankfully, X Speed appear often. When you catch up to Uxie, you'll have to attack it once with any attack (Water Pulse will work best since it's ranged) to get it to stop. You fail the mission if Uxie and the Commander meet up. You clear the mission upon successfully stopping Uxie.
Challenge Mode: X Speed's appearance rate is dropped to 65% of the previous rate.

Mission 3: "Destroy 50 GUN Hunters!"
Unlocked: Clear Mission 1 with silver-star rank, Clear Mission 2
Character: Gary
Upgrades Applied: Chaos Drives
On Radio: Prof. Oak
Mission: Destroy 50 GUN Hunter robots.
Detail: In this mission, your goal is to destroy all 50 GUN Hunter robots that appear in this stage for this mission. Don't worry about Dr. Eggman, Registeel, or the Team Plasma Grunts, none of them appear in this mission. If you manage to defeat them all, you clear the mission. The airplane does not appear in this mission either, so you can't leave the stage.
Challenge Mode: The quota is 100 GUN Hunter robots.

Mission 4: "That water's poison! Get out of here without touching the water!"
Unlocked: Clear Mission 1 with gold-star rank, Clear Mission 3
Character: Flint
Upgrades Applied: Materia
On Radio: Cynthia
Mission: Reach the GUN Airplane without touching the poisoned water.
Detail: One notable feature of Amazon Dense is its poisoned water. The poison prevents the water from being considered swimmable. This mission brings the Amazon Dense water into Metal Rapids. Once you've reached the end of the jet-ski run, you must proceed to make it to the GUN Airplane without touching the water. With so much of it going down the river, that's a difficult task, but it is possible. More specifically, there are rails going over the water where you would have to jump in and the rails also go over the closed tubes later on. You'll run into GUN Troops, including the signature Hunter robots, along the way, but facing them is optional. There are no humans other than mech pilots and yourself in the stage for this mission, so you needn't worry about the Commander or any GUN Soldiers not in a mech's thingypit. Once you reach the GUN Airplane, you clear the mission.
Challenge Mode: You must destroy all of the GUN Troops along the way to the GUN Airplane or you fail the mission when you reach the plane.

Special Mission: "Marine's in danger! Get her onto the plane without hurting humans!"
Unlocked: From start
Game Pak: Sonic Rush Adventure (DS)
Character: Pryce
Upgrades Applied: Chaos Drives
On Radio: Lance
Mission: Escort Marine onto the GUN Airplane without inflicting damage on any human.
Detail: A denizen of Blaze's dimension, Marine the Raccoon (her voice here is the same as that in Sonic Rush Adventure), has somehow made it into this dimension, and now GUN's set a price on her head! You'll meet up with Marine once you finish the jet-ski ride. Your goal is to make it through an area infested with GUN Troops, mainly Hunter robots as is usual, and make it to the GUN Airplane. You don't have to deal with the Commander here, but there are enough GUN Troops here for it not to matter. However, Marine will only accept the escort on one condition: that you don't harm any humans. Unlike usual, there are GUN Soldiers present in this stage, and if you do even 1 point of damage to any of them, you fail the mission. Mechs and robots are fair game, since any humans aboard them have the sense to eject, just don't hurt the soldiers not manning anything mechanical. Once you make it to the GUN Airplane, approach it to clear the mission.
Challenge Mode: A time limit of 14:00 is in place.
