Guide to ALL Sonic Content in the KartRider Rush+ Crossover [UPDATED MAY 5]

Since 2020, I’ve played (to my knowledge) every Sonic crossover collaboration in a mobile game. I beat up Mad Max rejects as Super Sonic in Fist of the North Star, I summoned Sonic as a demon in Shin Megami Tensei, and had an epic battle with my wallet in Cookie Run: Kingdom. However, of all the mobile games I dipped my foot into, only two ever took hold for more than a month: Ulala Idle Adventure, and KartRider Rush+. KartRider’s Sonic content has been broader and more involved than any of the other games I just mentioned, but if you want to get started with it, knowing where to find all the Sonic content is tricky (and potentially expensive) business.

[UPDATE] As of May 5, Tails and Chao are now available via the Monthly Pass, and the Dr. Eggman event has started. At this time, there are no future Sonic collaboration content updates we are aware of. However, if any do happen, we will update this article.

What is KartRider Rush+?

KartRider Rush+ is a mobile version of a very popular Korean kart racing game by Nexon (who you might know as the publisher of MapleStory). It features a cartoony style, a variety of game modes, a lengthy story mode with English-dubbed voice acting, and is free to play without timer restrictions. However, as it is a free to play game, many cosmetics, including many of the Sonic cosmetics, are only available if you pay for them. The game has gacha systems for certain cosmetics, but not for any of the Sonic content.

This is not an exhaustive tutorial of the game, but this guide will cover how to access the Sonic content, and how much it will cost.

What can I get for free?

Until May 10, you can redeem this code for Tails Headgear (a Tails face that hovers over your head, a Tails license plate, and a Chao license plate. To enter it, go to Settings (gear icon) > Account > Voucher Code. Passwords are region-specific.

EXPIRED: Until May 3, you can redeem this code for a free Sonic backback and “headgear” (a Sonic face that hovers over your head). To access code entry, go to Settings (gear icon) > Account > Voucher Code. Passwords are region-specific.

Until May 31, you can complete missions to collect “Sonic Letter Shards.” These shards can be exchanged for a Sonic aura, a Sonic Skateboard, a Ring Headgear, a Sonic Driftmoji (special effects that appear when you drift), Sonic Balloons (which are consumable when you equip them in item races, so be aware), and Ring decorations for your character’s home. The missions are daily, so you will need to play multiple days and complete them multiple times to collect every item.

The missions can be accessed from Events > Sonic Collection. The rewards can be accessed from Banquet > Sonic Collection.

Until June 16, you can unlock Sonic himself as a Kart (and a Sonic face mask) by completing special missions that will reward you with “Nitro Shards.” The mission screen then lets you convert a small number of Nitro Shards into a larger number of Ring Shards (yeah, I know, it’s bizarrely indirect). And as you collect more Ring Shards, more rewards unlock. Some missions repeat daily, and some repeat weekly.

At this point, I want to bring up that many collectables in this game are time-limited. I was annoyed by this at the beginning, but the game will throw a lot of time limited karts and clothes at you, so don’t take the limitation too seriously. By the time one free kart expires, you’ll have a different cool free kart to play with. Items list the number of days they’re available, or “Perm” if they permanently stay in your inventory.

Three tiers of unlocking Sonic are 30 days, 90 days, and permanent. If all you want is to dip into the game for free, try it out, play as Sonic, and then drop it, then 30 days might be good enough. Only you yourself know if it’s worth coming back every day to creep towards unlocking Sonic permanently.

This Sonic event can be accessed from the Sonic the Hedgehog icon on the main menu.

Until May 31, you can earn Dr. Eggman (Racer) as part of the “[Dr. Eggman] Secret Base” event. By completing missions, you’ll be able to flip over up to two of the cards on the grid and get rewards, including a Knuckles License Plate, Shadow/Tails/Sonic/Chao decals, Sonic balloons, and a 30-day unlock of Dr. Eggman himself. If you flip over all 20 cards, you’ll permanently unlock Dr. Eggman.

You can access the event via Banquet > [Dr. Eggman] Secret Base from the main menu.

Until May 31, you can earn Chao (Pet) as part of the free monthly Activity Pass. By completing weekly quests, you’ll earn Pass Points that increase your Pass Level (100 points per level), and unlock new rewards at each tier (up to Lv. 80). You can earn a 7 day unlock for Chao at Lvs. 2, 40, and 60. At Lv. 80, Chao unlocks permanently. At Lvs. 5, 25, 45, 65, and 77, you’ll earn Tails Balloons.

You can also earn a time-limited version of Tails (kart) at Lvs. 10, 30, 50, and 70, each adding 7 days and letting you play as Tails for free up to 28 days. You will need to purchase the Honor Pass in order to unlock him permanently (more below).

To access the Pass and Quests, go to the Pass icon on the main menu.

What do I have to pay for?

As of May 1, unlocking all available Sonic content costs a flat sum of $39, and requires actively completing missions and quests throughout the month.

If you want to unlock Tails (kart) permanently, he is available via the monthly Glory pass for $2.99. Once you pay, you immediately get a 7-day Tails unlock. As mentioned above, you need to complete weekly quests to gain Pass Points, gaining one level for every 100 points. Once you get your pass to Lv. 80, Tails will unlock permanently.

To access the Pass and Quests, go to the Pass icon on the main menu.

Things get a bit more involved from here on out:

Until May 31, you can unlock Knuckles and several other cosmetics via Red Star Ring Packs, which have a set price. The packs can be accessed from Banquet > Red Star Ring Pack.

Pack A is $8.99 and contains a different Sonic aura, Shadow balloons, some items, and a single Red Star Ring.

Pack B is $8.99 and contains a Dr. Eggman mask, a Shadow license plate and decals, some items, and another Red Star Ring.

Pack C is $17.99 and contains Knuckles (who is a driver, not a kart), Knuckles balloons and decals, and one last Red Star Ring.

To unlock Shadow (Kart), you’ll need the Red Star Rings from all three packs above. This puts Shadow’s price at about $36, though you’ll also get Knuckles and all the other Red Star Ring accessories and items.

Until May 31, you can unlock Dr. Eggman’s Egg Booster (Kart) by collecting ALL the other characters (which adds it to that $36 price tag to get Shadow and Knuckles, the temporary versions of Sonic, Tails, Chao, and Dr. Eggman are enough to unlock their part of the list). You can also earn 1up balloons, a Sonic avatar frame, a Knuckles glove on a wand, and a Sonic Team title on the path to completion.

The Egg Booster event can be accessed from the Final Battle vs. Dr. Eggman icon on the main menu.

Summary

I’ve personally spent more time in this game than I spend with many other full priced games I’ve purchased, and in that sense, I’ve felt justified in buying the Sonic cosmetics. However, I know not everyone is willing or able to simply spend $36+ on a mobile game. Hopefully this guide has helped anyone interested in the collaboration understand the costs involved, what you can get for free, and if the economics of this game are worth it to you at all.

For those who are interested in looking at the content but not buying or playing it, Sonic Stadium will have coverage of all these collaboration items on our YouTube channel as the event progresses. We’ve already started with Knuckles, Shadow, and the driver cosmetics:

Chu Chu Rocket! Universe coming to Apple Arcade

A new entry in Sonic Team’s long-dead Chu Chu Rocket franchise made a surprise appearance in an Apple press release today: Chu Chu Rocket! Universe.

The game is being developed by Hardlight, and is slated to come to the Apple Arcade service, a video game subscription service for Apple Devices that will let subscribers play a variety of games for $4.99 a month on iPhones, iPads, Apple TVs and Macs. It’s important to note that Apple’s press release specifies that it is a “mobile and subscription service” exclusive which doesn’t necessarily rule out console ports of the game, although devices that support Apple Arcade are the only confirmed platforms.

The game has 100 3D puzzle courses, and features gameplay that appears pretty faithful to the Dreamcast original: direct your mice to rocket ships without letting cats devouring them all. Chu Chu Rocket! Universe is slated to launch alongside the debut of the Apple Arcade service on September 19. Chu Chu Rocket! won’t be the only Sonic Team series hitting the service either: as we reported earlier this year, Sonic Racing will also be coming to Apple Arcade.

The Dreamcast original was the first game on the system to feature online play, so a sequel being announced a day after the system’s 20th anniversary is neat timing. This will be the first new entry in the franchise since the Dreamcast game was ported to iOS and Android back in 2011.

Nothing else is known about the game. Check below for a screenshot and game play footage:
