Sonic Adventure 3 (SONMART)

Sonic Adventure 3 (commonly referred to as SA3) is a 2017 platform game developed by Sonic Team and published by Sega,it is also a remake of Sonic 06. It was produced in commemoration of the Sonic series' 20th anniversary as a distraction from Sonic Forces. Players control Sonic, Shadow, and Silver, who battle Solaris, an ancient evil pursued by Doctor Eggman. Each playable character has his own campaign and abilities, and must complete levels, explore hub worlds and fight bosses to advance the story. In multiplayer modes, players can work cooperatively to collect Chaos Emeralds or race to the end of a level.

Development began in 2001, led by Sonic co-creator Yuji Naka. Sonic Team sought to create an appealing game in the vein of superhero films such as Batman Begins, hoping it would advance the series with a realistic tone and multiple gameplay styles.

Sonic the Hedgehog received praise in prerelease showings, as journalists believed it could return the series to its roots after years of mixed reviews. However, it was a success(not like Sonic 06).

Gameplay
Sonic Adventure 3 is a 3D platformer with action-adventure and role-playing elements. Like Sonic Adventure, the single player navigates through open-ended hub worlds where they can converse with townspeople and perform missions to advance the story. The main gameplay takes place in linear levels that become accessible as the game progresses. The main playable characters are three hedgehogs: Sonic, Shadow, and Silver, who feature in separate campaigns titled "episodes". A bonus "Last Episode", which involves all three hedgehogs and concludes the storyline, is unlocked upon completing the first three.

Sonic's story focuses on the speed-based platforming seen in previous Sonic games, with some sections having him run at full speed while dodging obstacles or riding a snowboard. Another character, Princess Elise The Hedgehog, must be escorted in some stages, and she can use a special barrier to guard Sonic. Shadow's sections are similarly speedy, albeit more combat-oriented, with some segments having him ride vehicles. In contrast, Silver's levels are slower and revolve around his use of telekinesis to defeat enemies and solve puzzles. In certain areas, control is switched to one of several friend characters, with their own abilities.

Although each character traverses the same levels, their unique abilities allow the player to access different areas of each stage and prevent them from accessing certain items. Scattered through each level are golden rings, which serve as a form of health. The rings can protect a character from a single hit by an enemy or obstacle, at which point they will be scattered and blink before disappearing. The game begins with Sonic, Shadow, and Silver each assigned a limited number of lives. These lives are successively lost whenever, with no rings in their possession, the characters are hit by an enemy or obstacle or encounter other fatal hazards. The game ends when the player exhausts the characters' lives. Every few levels, players will encounter a boss stage; to proceed, they must defeat the boss by depleting its health meter.

Upon completion of a level or mission, players are given a grade depending on their performance, with an "S" rank being the best and a "D" rank being the worst. Players are given money for completing missions; more money is given to higher ranks. This money can be used to buy upgrades for the player character. Certain upgrades are required to complete the game. The game also features two multiplayer modes: "Tag", a cooperative mode where two players must work together to clear levels and collect Chaos Emeralds, and "Battle", a player versus player mode where two players race against each other.

Plot
Doctor Eggman kidnaps Princess Elise The Hedgehog of Soleanna in the hopes of harnessing the Flames of Disaster, a destructive power sealed within her. Aided by his friends Tails and Knuckles, Sonic works to protect Elise from Eggman. Meanwhile, Shadow, his fellow agent Rouge, and Eggman accidentally release an evil spirit, Mephiles. The spirit transports the agent duo to a post-apocalyptic future ravaged by a demonic monster, Iblis. When Mephiles meets survivors Silver and Blaze, he fools them into thinking Sonic is the cause of this destruction and sends them to the present to kill him.

Throughout the story, Sonic and friends travel between the past, present, and future in their efforts to stop Mephiles and Iblis and protect Elise from Doctor Eggman. Though at first Silver stalks Sonic and impedes his attempts to save Elise, Shadow reveals to him that Sonic is not the cause of his world's suffering but rather Mephiles, who is trying to change the past for his own evil purposes. They travel 10 years in the past and learn that Mephiles seeks to bond with Iblis, who was sealed within Elise as a child, as they are the two halves of Soleanna's omnipotent god, Solaris. Mephiles eventually succeeds after killing Sonic to make Elise cry over his death, releasing her seal on Iblis and merging with him to become Solaris, who then attempts to consume time itself. The heroes use the power of the Chaos Emeralds to revive Sonic, and he, Shadow, and Silver transform into their super forms to defeat Solaris. Sonic and Elise are brought to the past and extinguish Solaris's flame, removing the god from existence and preventing the entire game’s events from ever occurring. Despite this, Sonic and Elise show faint signs of recalling their encounter afterwards.
