After fight with Shadow, Sonic travels 1000 years back in time with help of Maia and traps Lyric (Sonic also takes the map), then returns. Shadow also travels in time, but he teleports straight to the end of game. So yes, time travel is involved! Aren't you supposed to know that from the actual game?
