Freedom Fighters Sonic the Hedgehog, Tails, Johnny Lightfoot, Porker Lewis and Amy Rose were visiting the Green Hill Zone when they were alerted of heavy Badnik activity in the Chemical Plant Zone. Before Sonic can rush off to handle the danger, a voice asks if he is forgetting something. A confused Sonic realises the voice is Amy's and she means her. Despiting the list of times she hasn't been a liability, Amy is left behind in the Green Hill Zone. A frustrated Amy moans about her conflicted feelings for Sonic, but is pulled out with her stupor when she is attacked by six Buzz Bombers.
