Sonic The Hedgehog 2 Game Gear - Game cart + Manual
Like the previous games, players control Sonic the Hedgehog as he makes his way through each of the game's seven zones, fighting against various badniks and overcoming deadly obstacles. By collecting rings, Sonic can protect himself from damage against enemies and obstacles (with the exception of pitfalls and drowning), with extra lives earned for collecting 100 rings. Unlike the previous 8-bit title, Sonic is now able to recollect some of his rings for a limited time after being hit. Other technical improvements allow Sonic to smash through certain walls and run through loops. Also added to this iteration are gameplay mechanics unique to certain zones, such as riding a mine cart, using a hang glider to glide across the air, skimming across the surface of water and floating inside giant bubbles to reach higher areas. Unlike the previous game, the game no longer features the Shield and Restart Marker items.
Each of the game's seven zones consist of three acts, the third of which consists of a boss battle (most of which now consist of animal-based robots as opposed to direct confrontations with Dr. Robotnik) in which the player is not given any rings to collect. At the end of each of the first two acts, players can potentially earn bonuses such as additional rings, lives and continues by fulfilling certain criteria upon hitting the act's goal post, such as having a specific amount of rings. In the first five zones, a Chaos Emerald is hidden somewhere within the second act. These five emeralds, along with a sixth earned from defeating the sixth zone's boss, are required to access the game's seventh zone and ultimately achieve the game's good ending by defeating the game's final boss. Otherwise, the game will end after the sixth zone, with Sonic unable to rescue Tails.
