Chaos mode is a reimagining of an ancient gametype not seen officially in SRB2 since the Final Demo era. Unlike its predecessor, which was a simple and repetitive onslaught of enemies, this remake sees players completing timed objectives, exploring environments, and maybe even helping a friend or two along the way.

Features
  • A cooperative gametype supporting both solo and multiplayer gameplay
  • Eight maps total; seven familiar, and one built from the ground up
  • Music: 4 new bgm tracks and 2 new jingles
  • Randomly generated spawnwaves
  • New enemy challenges, reworked enemy mechanics, and overhauled AI
  • Cooperative ring sharing mechanics
  • Automatic server difficulty scaling
  • Type chaos in console for a list of useful cvars and commands for players, server hosts, and modders
  • Supports most custom characters

In this mode, you must destroy egg capsules and other key targets before time runs out! Enemies and objectives appear in waves, and the level is completed once all waves are cleared.

Life is easier with company! Press tossflag to share some of your rings to an ally. If you don't have any rings, tossflag will signal to other players that you need help!

To configure ZoneBuilder for Chaos mode, simply add the main Chaos pk3 as a resource under SRB2 2.2 configuration settings. See the wiki documentation for more details on mapthings and mapheader settings.

For enemy configuration, two example pk3s have been included with Chaos mode, including lua documentation that can be viewed using SLADE.

This is pretty good what am i saying ITS AMAZING anyway i think its really cool concept you have 6 or 8 waves and you have to kill the bosses in each one i mixed multihit mod with this and i really like it bc it made badniks more challenging overall good job

I absolutely love this game mode. I usually play as Modern Sonic which works pretty well. I also like to pair it up with Roll The Dice Deluxe for added fun.

The only complaint I have with this is during the last round, the framerate drops horribly down to like 5 FPS. At first I thought it was my crappy 2GB memory laptop, but then I played on my Samsung S21 and the frame drops still happened, so it can't have been a specs issue.

Aside from that, this mode is fun as hell for a singleplayer experience and dare I say preferable to the campaign mode. If the frame drops get fixed, it would get a five-star rating from me.

personally, if you're bored of the vanilla gameplay formula, then THIS IS THE JAM
this is legitimately the best non-pvp gamemode i've seen that doesn't stray from srb2's base gameplay
the best part about it is that it also acts as a QOL mod, making enemy combat better by making enemies more aggressive overall and making the thz and gfz bosses ACTUALLY FUN (for the most part maybe not the THZ boss)
and nothing matches the feel of having an attraction shield, while super, and having collected all the rings so you get silver rings
absolutely amazing

I love Chaos mode. This mode is at it's best in single player (solo). I didn't enjoy it as much in an online game (with friends or randoms) but it is still enjoyable. Plus, the addition of Spring Yard Zone made it much better. Every other map (except for Tidal Palace Zone) are very solid maps as well (Techno Hill Zone is probably my favorite zone in this addon). It kinda suffered some of the issues with Battle mode in Kart racing games, but these issues are very small (and more noticeable in multiplayer) and can be overlooked. Overall, I love this mode and would recommend to anyone.

I am absolutely blown away.

I had a chance to play it solo on the Iron-Turret-looking zone. I was surprised at how well the waves would flow from one to the other; despite the map size being relatively small, each wave would introduce elements that kept exploring the map fresh. It would produce a non-linearity that was very Sonic Jam meets SM64 to me, and the difficulty kept it engaging to the end with only 1 player.

It honestly made me tear up a little as I made my way to Eggman. It's fantastic how even the least-played game mode of the 108 era could inspire such a creative re-imagining over a decade later. This is a perfect encapsulation of the spirit of Chaos mode. Great job!
