Sonic Robo Blast 2, abbreviated as SRB2, is a fan game for Windows and DOS platforms. It is a 3D platformer developed by a group called Sonic Team Junior, using a modified version of the Doom Legacy source port of Doom, to allow for such things as optional analog control and true room-over-room (something not possible in the standard Doom engine), as well as the standard gameplay elements Sonic games are known for. It has been in the works since 1998 and is currently nearing completion, though several parts of the game are still missing. Sonic Robo Blast 2 is closely inspired by the original 2D Sonic games for the Genesis and attempts to recreate a game with this style in 3D, though it also borrows elements from the current Sonic games, such as Sonic's signature Air Spin Attack. Entirely original to SRB2 is its Multiplayer mode, a variation of classic first-person shooter games with Sonic elements. Due to being built with a modified Doom Legacy engine, the game is also very easily customizable. Custom levels, characters and even source code modifications can be created with the help of external editors.

SRB2 TGF (or SRB2 The Games Factory) was the first version of SRB2, which was developed between March and July 1998 before being scrapped. Unlike all following versions, SRB2 TGF was still a 2D game, created with the game-making tool The Games Factory. Compared to Sonic Robo Blast, SRB2 TGF was considerably more advanced: It featured monitors, springs, shields, spikes and the ability to spin on the ground. The levels included features such as water, moving platforms and mine carts. Enemy collision was much less buggy and the player could now bounce off enemies and monitors. SRB2 TGF was later scrapped to be released as the 3D game in the Doom Engine.

Sonic Robo Blast is an early Sonic fan game from 1998, created by Sonikku, real name Johnny Wallbank, of Sonic Team Junior. It is one of the earliest Sonic fangames to exist and led to the founding of Sonic Team Junior as well as the eventual creation of it's sequel, Sonic Robo Blast 2.
