An empty Challenge Act Gate.
- For the Open Zone Challenges in Sonic Frontiers and Shadow Generations, see Challenge.
Challenge Acts are stages that appear in the console/PC version of Sonic Generations, and later Shadow Generations. They are mission-based levels that the player can participate in.
Overview[]
Challenge Acts are accessed via Challenge Act Gates in the area above each Stage Entrance in White Space.
In Sonic Generations, there are ninety Challenge Acts; each stage has five for Act 1 (Classic Sonic) and Act 2 (Modern Sonic). Completing the first Challenge Act for any area unlocks a Boss Gate Key, and completing all of an areaโs challenge acts with one character will restore a bit of color to the actโs Challenge Area.
In Shadow Generations, each stage has, initially, two Challenge Acts for each Act, with the exception of Radical Highway, containing no Challenge Acts. The Boss Gate Key can only be unlocked by clearing both Challenge Acts for corresponding action stage. After Doom Zone activation becomes available for the player, a third Challenge Act will appear for each act, being the Hard Mode counterpart of the existing Challenge Act.
In addition, any Challenge Act the player completes will cause a Bonus Bell to appear above the Challenge Act Gate that, when rung, will spawn a roaming musical note that unlocks a random music track or piece of concept art.
