SeventhSentinel--err I mean, Sonic explains the v1.1 patch update


This game has absolutely no single player content outside of time attack. There are no CPU players. To get the full experience, you have to rely on either splitscreen or online multiplayer. While hole punching is now available as of v1.4, you may require port forwarding to host games. The port to forward here is 5029, UDP.

It should be noted that this game has absolutely no clientside prediction whatsoever, and runs on a fairly antiquated client/server networking model. It's extremely likely that you will experience latency in some form. Make sure you join servers that you have a low ping to, even if another server has more players. This will help create a better experience for players across many different regions.

Now without further ado, in Sryder's own words...


SRB2Kart is a classic styled kart racer, complete with beautiful courses, and wacky items. Of course, because it’s SRB2Kart, it has a Sonic twist that really shows the classic charm that a lot of us know and love from the good old days™.

We have 100 jam-packed maps for you to bump, explode, and sparkle your way through, from luscious beaches, to Eggman’s dance floor, to England on a good day. All lovingly crafted by many different people. You’ll notice almost every aspect of the game has an immense love and inspiration from the classic sonic games. From the items such as Ballhog, which literally throws bouncey explodey balls at people, to the maps which are bursting with that Sonic feel.

Of course, you'll only start off with a few cups available, but you can unlock more by playing offline/online matches. Alternatively, you can immediately jump into challenging yourself and race us personally in Staff Attack mode! Don't worry, we'll go easy on you.

Game Modes
We have 2 game modes for you to choose from: Race, and Battle.
Race mode is the normal: Race through the track to beat your opponents, use your items and skill to swooce past the competition, Oh my God what is that following behind me HELP! You know, the usual.

Battle mode asks you to violently throw spikeballs at your friends until they have no bumpers and you have some. But watch out, they can come back with a vengeance and chase you to the ends of the earth afterwards! Or maybe if they’re feeling nice they might help you with a powered up item

As you’ll find, we have 5 characters in the base game to enjoy, all with very distinct stats. Before we go into them individually, I’ll explain how our stats work. We have separate variables that effect the way a character plays. Speed, and Weight. Higher speed gives you a greater top speed, but sacrifices your ability to accelerate, higher weight reduces your control over your drifting, but you bump players that you are heavier than more violently. Your combination of speed & weight decide how fast you earn drift sparks. We have this shown clearly on a handy dandy grid on the character selection screen in the main menu, pick the character that aligns with your desires most!


Sonic is just what you’d expect from our favorite blue hero! Pretty fast and agile! He’s got some good speed, and can control his drifts pretty well, just make sure you get the drift boosts because otherwise you’ll fall behind!


Our cute fox boy Tails! Tails has slow speed, but can really get going quickly, he can also take incredibly tight turns all the time, get close to those corners for him to really slip past people!


Here he comes, tougher than the rest of them. Knuckles is average in both stats, he’s very balanced, and likely a good pick if you don’t know who to try first!

Dr. Eggman

Ohohohohoho! Eggman has come along to steal the competition! He’s quite slow though, so take advantage of his fast drift-spark rate and his immense weight to stop others from overtaking!

Metal Sonic

*Loud Angry Robot Noises* Metal Sonic is fast, and heavy. He’ll fly through the courses if given the chance, but his cornering leaves much to be desired…

Bonus Ducks Characters
Included with the main download is bonuschars.kart. We don’t add it by default, but you can easily do so from the add-ons menu for many more characters to play with! A slew of extras, by a trio of our other devs in their free-time, as well as a few Community artists!

The Various Other Things
-Make sure to check out the in-game manual by pressing F1 or using the menu if you need some help or tips!
-We’ve added some extra Quality of Life features from the vanilla game to help out, such as multi-admin and a chat system that is readable!
-There’s a slight lack of documentation for modding currently, we’ll try and get on that as soon as we can.

We plan to redo the crediting in some fashion eventually so all the track sources can be included in-game, but until then they'll all just be right here for very easy viewing!

Even if you have the game already, you want the Full Install. Previous versions offered a Patch to save on download size, but v1.4 is a significant enough update that we encourage you use the full installer over your existing installation.

Full Install for v1.5 (Windows)

(Mac and Linux installs not yet available for v1.4, please wait patiently...)

The changelogs for every single update can be found here: https://github.com/STJr/Kart-Public/releases

MANUAL (F1 in-game)

The non-Windows builds are experimental and haven't been tested nearly as much; if you have issues, you can always attempt to compile it for yourself on your own computer: http://wiki.srb2.org/wiki/Source_code_compiling

I have no idea what was going on with holepunching.

This is a review for the 1.4 update and not the game itself.

Hole-Punching seems to barely work. My friends and I don't see our servers, and when we do join a server, chat messages start repeating over and over. Works, but barely.

I've been playing and looking at the development for this "mod" for three years, heck this isn't even a mod anymore, This is a full-on game! DO NOT COMPARE THIS TO AAA Games. This is it's own love letter to Racers.

pretty good game. but not as fun as normal srb2 in my opinion. this is my first time playing the game to, so maybe i'd have a review with higher stars when the game gets less boring for me. but overall, its a good game.

Easier and Amazing Addons, Very Fun, and the foundation of the first time playing SRB2. Better than Mario Kart.

SRB2Kart v1.3 is one of the best racing games I've ever played. Granted, I'm not a connoisseur of the genre, but I've played some Mario Karts in my time, and Nintendo does a good job there, but SRB2Kart is just incredible. It has a ridiculously high skill ceiling, which on one hand, can make it a bit harder to find people of an equal skill level, and harder to get newbie friends into the game, but on the other hand, learning the ins and outs of the game and getting good enough to get most of the Record Attack medals is incredibly rewarding. Even with the single-player content being largely unfinished with the exception of Record Attack, there's still an incredible amount of fun to be had. Also the item design is a very big part of why I think I enjoy this so much more than other kart racers that I've played. The SPB, or Super Propelled Bomb, doesn't just go to 1st place and beat them to death like a Blue Shell might, it just chases after them at the same speed, meaning 1st has to play perfectly, or else lose a big lead on the other racers, making frontrunning more about skill under pressure, in 1st place, or in 2nd place and back, about good use of items to trip them up, and strategizing whether to fight the other opponents behind you or to fight those in front. Jaws is a bit more interesting than a Red Shell, because instead of following the track, it locks onto a target and goes towards their back at all times. This can allow you to trick the Jaws into destroying itself, if you can quickly turn around a wall faster than Jaws can get past it. And my favorite, the Eggman Box doesn't just spin you out for a second, it gives you a countdown until you explode. You can mash the item button to make this go off faster; so if you're annoyed that you hit it in the first place, you can try to surround yourself with other people to drag them down with you. Almost all the items are designed like this; my only complaints with them is that Shrink and Grow kind of serve the same purpose, just in different ways, and Grow stays in your item box while it's in use, which isn't great when you're too far to catch up and squish someone to create extra distance for yourself. Of course, you can cancel it which works too, but that's hard to remember. Either way, I'm not too broken up about this because I've heard it's being fixed in V2 anyway.
The other great thing about SRB2Kart is the incredible community support. If my memory is correct and I counted right, at least half of the characters from Super Smash Bros. Ultimate at this point have been modded into the game at this point, along with dozens of other characters you'd never in a million years expect from an official SEGA or Nintendo product. It's become sort of a racer MUGEN at this point, and it's beautiful. Overall, the great game design and the community mod support come together to create a truly magical experience.

This thing's pretty much the most fun I've ever had in my life.
Gameplay mechanics are extremely solid and the track design is excellent, both from the vanilla game and community content.

My copy of Mario Kart 8 Deluxe (Ew) is dying buried under dust since I started playing that more often.
