Review of Sonic & Knuckles

great game as all the sonic games are for mega drive
it has good music tricky levels

game as a lock on cartridge which allows you to play as knuckles in Sonic 2 if you join sonic 2 with the sonic and knuckles cartridge

also if you have sonic 3 cartridge you put sonic 3 on top of the sonic and kunckles cartridge and this will allow you to play as kunckles in sonic 3



9/10
