games/SRB2: 3D Sonic the Hedgehog fangame
Sonic Robo Blast 2 is a 3D open-source Sonic the Hedgehog fangame built using
a modified version of the Doom Legacy port of Doom. SRB2 is closely inspired by
the original Sonic games from the Sega Genesis, and attempts to recreate
the design in 3D. While SRB2 isn't fully completed, it already features
tons of levels, enemies, speed, and quite a lot of the fun that the original
Sonic games provided.
