Sonic comes running to help Chris' group from their predicament, but the Chaos Emerald ends up being robbed by Eggman. When Sonic and the others follow him to his base, a battle between Eggman and the government's military unfolds before them there. Rouge, Knuckles, and the others who infiltrated the base set up a bomb in the power sector and attempt to escape, but they are locked up by the shutter door. Sonic has to take it upon himself to obtain the (cyan and yellow) Chaos Emeralds and defeat Eggman. (Source: Wikipedia)
