Sonic The Hedgehog (Sega Master System) game description
The game sees players playing as Sonic the Hedgehog as he travels across South Island to steal it from the evil Dr. Ivo Robotnik. Sonic is able to attack enemies by performing a Super Sonic jump Attack, either by jumping into the air or rolling on the ground, the latter of which can also send Sonic off ramps.
By collecting rings, Sonic can protect himself from damage from enemies and obstacles. Sonic will lose a life if he is hit without carrying any rings, or if he drowns or falls into a bottomless pit. Items found throughout the game include extra speed, speed shoes, everlasting invincibility, shields and checkpoints.
Throughout the game, Sonic travels through six zones, each consisting of two main acts and a boss battle stage. At the end of each main act, the player hits a Goalpost which can award bonuses depending on how many rings Sonic is carrying. If the player has over 50 rings, they can access a bonus stage where more rings and continues can be collected. In each zone, there is a Chaos Emerald hidden somewhere in one of the acts, with a good ending awarded if the player finds all of them and completes the game.
To stop the evil Dr. Robotnik, Sonic must traverse six zones consisting of three levels each. Most of the zones are based on those in the original game, but some are entirely new, including a jungle environment and a huge airship. Other unique differences are one level that scrolls automatically and one that is aligned vertically instead of horizontally. Most of the enemies (mechanized animals, defeated by Sonic’s spikes when jumping or rolling) and power-ups (speed-ups, shields, extra lives) are the same as in the Genesis version as well.
