Demo 3 is an outdated version of SRB2, released on June 23rd, 2001. This demo was released to celebrate the 10th anniversary of Sonic 1's release. It introduced multiplayer gametypes, which at this time included Match, Race and Tag mode. A roster of five Match levels was introduced, of which one, Tag Valley Zone, was specifically devoted to Tag mode. At this time, Tag was extremely popular amongst netgamers, who had, in the past, only been able to play Match mode. At this point, Race was based on Sonic 2's split screen mode, and was intended to be played in the Single Player levels.
Demo 3 also included modifications to Techno Hill Zone Act 1. The slime was now damaging and the fan platforms in the factory part were replaced with the current pipe gimmick. Other minor improvements and fixes were made to the existing Single Player levels, such as a modification to the lake outside GFZ2's crawla pen to prevent the player getting stuck. Tails' walking animation had now been completed for all angles. A placeholder sprite for Knuckles' gliding ability was also added, though all other sprites for Knuckles still depicted either Sonic or Tails. The analog control option from SRB2 Christmas was re-added in this demo in a more finished state, now making the player face the direction they were moving in. Rings were now spilled in a circle around the player, rather than randomly in all directions as in previous demos. The player now had a little control over their movement while spinning; they could hold the back button to slow down, or hold forward to move faster. However, the ability to move faster while spinning was removed in Demo 4.
Aside from Sonic, Tails and Knuckles, three additional community-created characters were included in Demo 3, never to be included in SRB2 again afterwards – these were Chao, Cinossu, and Megaman, which were some of the first custom characters created for SRB2:
- Chao was a character made by Rlan (the founder of SFGHQ) in June 2001 that had no double-jump ability.
- Cinossu was a Sonic recolor, made by Cinossu also in 2001, that had Sonic's thok.
- Megaman was a character formerly available to download from srb2.org, consisting of sprites ripped from Mega Man Soccer and Mega Man 7, that also had no double-jump ability but was able to shoot with the use of the Ring Throw button.
All three of these characters were also able to spindash (it was not yet possible to disable spindashing), and otherwise had identical gameplay to the main characters.
Demo 3 was the first version to award the player with an extra life for every 50,000 collected points. At this point, the extra life was not yet awarded immediately but rather at the start of the next level.
