Rouge: The Bombardier is the third Challenge Act of City Escape Act 1 in the console/PC version of Sonic Generations. It is unlocked after clearing every Stage in the Dreamcast era and is playable only as Classic Sonic.
In this Challenge Act playable only with Classic Sonic, Rouge the Bat attempts to prevent the player from reaching the Goal. Throughout the mission, Rouge flies ahead of Sonic in the background, pausing at set intervals. She occasionally throws Heart Bombs at Sonic, who must avoid touching them or else lose Rings. In addition to this threat, obstacles such as seesaws and spikes keep the hedgehog on his toes. Once Sonic passes the Goal Post safely, the Challenge Act is completed, and the player is ranked according to his/her time.
