Sonic the Hedgehog: Full Edition

Sonic the Hedgehog: Full Edition is a downloadable game for the 3DS.  It is made to celebrate the twenty-five years of Sonic, similar to how Mario got a remake of Super Mario Bros. on his birthday.  The game keeps everything in the game, but adds new stages and challenges, plus new modes!
==Modes==
===Classic Mode===
This mode plays like the original game!  There are seven zones, all item boxes are from the original game, and you also cannot spindash unless you turn it on in "Classic Options".  Tails can be played by holding "B" and start and Knuckles can be played by holding "X" and start.  You may play with two players in this mode, as Sonic and Tails.  Hold "Y" and start to start up the mode with the duo.
===Extra Mode===
Extra mode adds two new zones (and bosses), adds the Sonic 3 monitors, and adds cutscenes.  Sonic, Tails, or Knuckles can be selected from the character select, and you have to play as any one of them through the whole game.  Bosses have added techniques and some bonuses are added.  A seventh emerald is added to this mode, and if you get all of the emeralds, you can turn into your super form.
===Time Attack Mode===
In this mode, you can race on any course, as long as you've completed it in Classic Mode.  Beat the clock and set up world records!
===Versus Mode===
You and another player must race each other on a course, and make it to the end before the other!  As bosses cannot be fought, Final Zone is not playable.
===Challenge Mode===
You can do challenges here!  There are five challenges in every mode.  After you do a mission you get a Sonic Token.  These can unlock stuff in the Galery and add to the sound test, plus more!

==Characters==
Character 	Image	Description 	Unique Abilities	In Original Game?
Sonic 	 	The blue blur is back in his old days!  With no time to waste, he's going to save all of the animals!  Can he stop Dr. Robotnik again?	
*Roll
*Spindash (can be set in options)	Yes
Tails 	 	The best bud of Sonic is back!  In extra mode, anyway.  He can fly, but there isn't much else to him. 	
*Fly 	No
Knuckles 	 	The knucklehead returns to the battle, but in extra mode.  He can glide and climb walls, and he can break certain types of walls. 	
*Glide/Climb
*Wall Breaker	No
Metal Sonic 	 	Metal Sonic is only seen in Missions Mode, where in the second mission of the second act of a zone you must beat him to the end! 	*Race Character*	No
Dr. Robotnik	 	Dr Robotnik is back to enslave and roboticize all of the animals!  Will he succeed (for once)? 	*Boss* 	Yes
==Zones==
Zone 	Description 	Theme 	Order in Original	Order in Extra	Is it in Original Game?
Green Hill 	The first, most famous zone of the series!  The top part of the stage is beautiful and rather simple, but closer to the bottom you can fall off and spike pits are more common.  Waterfalls can be seen roaring in the background, and there are some in the stage itself!	Hills 	1 	1 	Yes
Marble 	Marble zone is kind of out of place, because it comes right after a peaceful zone!  Temples and lava are everywhere!  The stages are actually rather short, but you go up and down quite a lot. 	Dark 	2 	5 	Yes
Spring Yard 	Who could forget what started up the casino theme?  Springs, bumpers, and some tough enemies will hinder some of your progress, but some actually may enjoy the bouncy madness. 	Casino 	3 	2 	Yes
Bone Desert 	A new level!  The Bone Desert is the speediest zone in the game.  You can run through several loop-de-loops and spin in the underground tubes! 	Desert 	- 	3 	No
Labyrinth 	The frusturating Labyrinth Zone makes a comeback!  Water covers up a vast amount of the stage and there are little rings to save your life.  This is probably the hardest zone in the game... 	Aqua/Maze 	4 	6 	Yes
Star Light 	Star Light!  This is the speediest zone in the game, aside from the extra "Bone Desert".  The top is all about loop-de-loops, but the bottom requires precise and careful movement. 	City 	5 	4 	Yes
Vile Mountain	Vile Mountain is very dangerous!  Lava is everywhere and many enemies threaten your existance here.  The third act is mechanical and actually has freezing water instead of lava! 	Volcano 	- 	7 	No
Scrap Brain 	The last big zone of the game!  The first act has many pits to fall into and is based on a city mixed with factory elements.  The inside, in act 2, is much more like a factory, and flamethrowers and saws are much more common. 	City/Factory	6 	8 	Yes
Final 	The final showdown!  Stop Robotnik here and save the day! 	Factory 	7 	9 	Yes

The second attack (besides the Egg Crushers boss) is an extra attack added in Extra Mode.
