Sonic Robo Blast 2 is a free 3D Sonic the Hedgehog fan-game built using a modified version of the Doom Legacy source port of Doom. SRB2 is closely inspired by the original Sonic games from the Sega Genesis, and attempts to recreate their design in 3D.

SRB2’s features include:

• Beautiful 3D environments with free movement in all directions.
• Old-school platforming action complete with rings, springs, badniks, spikes, and other obstacles.
• Multiple playable characters each with their own unique abilities.
• Over 25 levels to zoom through and explore, featuring a variety of locations ranging from green meadows to ancient ruins to space stations and more.
• Cool, sweet, and catchy soundtrack produced by a roster of talented musicians.
• Fast-paced multiplayer fun with 2 player splitscreen or up to 32 players online in many different game modes.
• Flexible control options so you can play with keyboard & mouse or almost any controller.
• Customize the game with your very own levels, characters, and game modes, and more. With the right skills, you can turn it into a whole new game.

…and so much more!
