How do you get supershadow in sonic robo blast 2?

Answer 1

First of all, Shadow is not a character initially in SRB2. You must download a .wad file of Shadow and add it by pressing the ~ key on the title screen and typing "addfile wadfiel.wad." If you have the right variation of the wad, then Shadow will transform when 50 rings are obtained and you jump twice after getting the 7 emeralds, just like Sonic does.

Answer 2

First of all: Shadow isn't initially in SRB2, and can only be obtained via a port of the WAD file from 2.1.25. Wait until the official port comes out, or do a port yourself, using Slade.

After that, do what your instinct tells you to do to turn Super - get all Chaos Emeralds, 50 rings and lose any shield you might have at the point of time. Jump, press Spin, and - voila - Super Shadow.
