Reverse Block 2 takes place in Guardian Rock. Much of the course through this extra stage leads down a route expanded upon with blocks and unbreakable Containers.
Reverse Block 2 is played entirely from a 2.5D side-scrolling perspective. In terms of layout, this extra stage is a straight path with a number of twists and turns.
Much of Reverse Block 2 includes transparent yellow blocks, which are the main gimmick of this extra stage. These reverse blocks can be destroyed with any of the playable characters' attacks. However, the blocks will respawn in the same position a few seconds after their destruction.
In some situations, the player has to destroy the reverse blocks in order to move on. In other situation, the player is obligated to use them as platforms. In the latter case, enemy Egg Pawns will occasionally shoot the reverse blocks when Sonic/Shadow is standing on them so they will lose their footing.
When beginning Reverse Block 2, simply follow the path on the right. Eventually, the player will run down a slope with a Spring at the end that will send them flying towards a staircase of reverse blocks. The player must scale these blocks quickly and make it to solid ground on the right, as Egg Pawns will attempt to destroy the blocks upon the player's arrival. After a brief trip along solid ground, the player has to cross another gap by using reverse blocks as platforms, all while Egg Pawns shoot at Sonic/Shadow. Upon making it back on solid ground again, keep following the path ahead to reach the goal.
