Sonic
the Hedgehog 2 follows in the same speedy footsteps as its
well-regarded predecessor, Sonic the Hedgehog. Once again, players run,
jump, and spin the blue hedgehog through a bizarre world of metal robots
created by Dr. Robotnik, avoiding obstacles, trouncing enemies, and
collecting rings and the elusive Chaos Emeralds (earning all seven
emeralds turns Sonic into Super Sonic). While the basic action remains
essentially the same, the levels are longer, the colors are brighter and
more varied, all the zones are new, and the game introduces a new
character: Tails the fox. In the standard game, Tails simply follows
along, helping collect rings and defeating the occasional enemy, but he
is a playable character in the special two-player split-screen race
mode. Sonic the Hedgehog 2 also introduces a new move (the Spin Dash)
and a new special stage: a challenging, pseudo-3D race through tubes to
collect rings.
