Sonic Generations + DLC for PC :

Sonic’s universe is thrown into chaos when a mysterious new power comes into force, creating ‘time holes’ which take Sonic and his friends back in time. While there, Sonic runs into some very familiar characters from his past including a younger, classic version of himself! Now they must defeat their enemies, save their friends, and find out who is behind this diabolical deed. 
Play as both Classic Sonic and Modern Sonic in the ultimate Sonic experience. Master the moves of each character as they race through each environment on their own specially designed track.
