Robotnik is a pain in the ass and he's now turning innocent animals into robots to build his ultimate weapon. This time around Sonic will receive some help from Tails. But now Sonic is back to kick some ass on mobile devices, and also on PC, as proven by this Sonic The Hedgehog 2 available on Steam. In his youth, he took part in a fierce battle with Mario Bros, but the blue hedgehog became eclipsed whilst the plumber is still the main star of many modern games. If back then you were a SEGA gamer, whether on Mega Drive, Master System or Game Gear, you surely played more than one game featuring Sonic.
