Go on a Mission

Robotnik hired you, or you're working on his side for whatever reason you chose(or against your will), to destroy the Freedom Fighters and stop any attacks they may initiate on Robotropolis. Capture any Freedom Fighters for immediate interrogation and eventual roboticization.

Mission ideas: Cause Mayhem in the forest. Nothing irks the Freedom Fighters more than destroying their forest. Attack Freedom Fighters, defend Robotropolis, search for and capture freedom Fighters, recon, patrol missions, etc etc!
