A top Sonic game with plenty to offer.
It introduced two new faces Metal Sonic and Amy Rose but did not feature Tails but the Enemy was Dr Eggman AKA Robotnik. The zones had time posts like future and past and the levels were different. The bosses were some of the best in a Sonic game made. You had to collect time stones from special zones where you had to destroy these UFOs to achieve one but water made the time go faster. It had the best bits from Sonic 1 and 2 in and is a very well made game.
