Sonic 3: Chaos Adventure


A fan-made sonic game with based on Sonic 3 called Chaos Adventure.

Author Note:

This is one of my (Jdpense) main Sonic 3 and Knuckles hacking projects! This hack is a demo that contains a completely new gameplay mechanic I that came up with and developed. This gameplay mechanic allows the player to store a limited amount of powerups the their inventory, so the player can choose when they want to utilize the power up they collected.

This is a project that I have been working on for several months now, so I want showoff this project and receive feedback on. This will be one of my main projects that I will persist to keep working on!

Playable Levels:
– Angel Island Zone Act 1, 2, and 3

Playable Characters:
– For this demo, Sonic is the only playable character. The reason is that I plan to come up with new powerups and level design changes specifically for the other characters that I didn’t have the chance to get to yet.

– New inventory mechanic for powerups
– New Sound effects and Drums samples from Sonic CD and Knuckles’ Choatix
– New level design built from scratch to work with the new game mechanic
– New powerups such as the Combi-Ring (from Chaotix), Rocket Shoes, and Pogo Spring (from Sonic Choas) and etc.
– New HUD display, voice samples, End Results display, and so much more!

Instructions for the new gameplay mechanics:
-Controls for usage of Inventory:
– Swapping powerups: Press B while NOT jumping nor airborne. (Standing or rolling on the ground.)
– Utilizing items: Press Jump (A or C) then the B button to use the power up displayed at the TOP of the inventory.
– Controls for usage of Exclusive Character Powerups:
– Pogo Spring:
– Press and hold DOWN on the D-pad to increase to height of the bounce.
– Rocket Shoes:
– Press LEFT or RIGHT on the D-pad to alter Sonic’s direction on the horizontal axis.
– In order to leave the powerups, press A or C.
– A and C are both still jump.
– Storing Powerups to Inventory:
– By simply breaking a monitor, the powerup from the monitor will be added to your inventory. (Excluding 1 ups and super ring monitors. They automatically get added to your life and ring counter.)
– It’s also important to note that the player can only carry 3 power ups at a time. If your inventory exceeds this number, then the powerup displayed at the BOTTOM of the inventory will fall out of your inventory as a bouncing icon. You can still collect it and restore it to your inventory, by touching it before it disappears!

Tools Used:
– SonMapED
– SonED 2
– JMan’s Sonic 1 Sound Compressor
