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 v1.6 (Windows)

Universal binary for v1.6 (OSX)

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

This is one of the best games I've ever played. I can't wait to get my own personal Windows PC so I can play this once again.

1.5 Is a good improvement with built in frame interpolation. Dedicated server is broken though :( You can compile your own, they also took all the original textures off Koda, which I disagree with. It would be better if they had a way to let users choose. I get it, epilepsy, but this entire game is epilepsy inducing. Let the map be what it was meant to be, without the wild textures on it, it's just a bad map. They are what made it good.

Anyway, over all good but there are some things they should work on, mostly involving local multiplayer.

Easy fixes:
1: Let player 2, 3 and 4 configure their own character.
2: let voices and combat sounds be louder in 3 and 4 player split.
3: Fix dedicated server. (this is redundant, obviously this will be done but im listing it anyway)
4: Fix the UI bug where admins can't actually change the auto spectate timer in the menu.

Hard/Possibly impossible fixes:
1: Allow users to toggle alpha transparency if possible for low spec systems.
2: Optimize 4 player split in general, currently you lose 70-90% performance (should be closer to 40%).

Feature requests:
1: Implement a better character select screen.
2: allow servers to automatically collect ghost data randomly so single players who join can race against ghosts. Maybe top 3 fastest times, and a random scattering of other complete times.
3: Have circuit points award "emeralds" every 4-5 races and then reset the total points. This way sessions are divided into "circuits" and there is some cycle competition. Right now circuit points are mostly a measure of whos been online the longest. Emeralds would only be cosmetic on the post-race page. Or perhaps you could have it swap star power music/visual with a yellow/white glowing super sonic music/effect if you manage to get 7.

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.
