So for those who never played this before, Sonic 2 Robotnik's
revenge or the commonly shorten term Robotnik's
Revenge is a hack of sonic 2 created by ColinC10 in 2008. basically the point of this hack is more or less a time attack/Survival hack where players must beat a combination off all bosses from both sonic 1 and sonic 2 on the death egg. and that's pretty much all there is to it. so if you want a try at this, you can get it down below.
