Sonic Robo Blast 2 (often abbreviated SRB2) is a platform game made within id Software's Doom engine. It is a free Sonic the Hedgehog fan game inspired by the original Sega Genesis games that "attempts to recreate their design in 3D", and was the first fan-made 3D Sonic game created. The game has received consistent support throughout its development of over 20 years, which has been attributed to a large modding community
Mario: Mario is slower than the main cast, but he has faster acceleration than anyone else. He has a huge move set that can help him get almost anywhere. By jumping, Crouching, Using the hammer, or power ups that lie inside monitors, you can play the levels in any way you like!
Luigi: Plays just like Mario, but slightly different by comparison. He can jump higher but can't run faster like he does in the games. He's also more slippery to take caution if you're in a platforming segment. Luigi also has extra moves in his move set.
