Sonic Adventure 3: Father of the underworld is the next installment of the Sonic Adventure series set after the events of sonic adventure 2. This game features new gameplay elements and includes hd graphics. It is for the nintendo Wii u coming in 2012.


The gameplay is akin to the style of the sonic adventure series but also keeping some of the gameplay styles used in sonic unleashed, colours, and generations gameplay. There are also Adventure fields in full 3d like in Sonic unleashed and Sonic adventure and Sonic 06. And if every stage is completed with an a rank you get to face off against the true final boss. Also turning becomes easier as to when in the more recent games sonic makes a loose turn which gives slippery controls but now characters do a 360 degree turn in one spot like in sonic adventure. The Chao garden mini game will also carry on like SA1 & 2. There is a new option for each character to switch the genre of the game play, there are 9 different styles of gameplay these are :

  • Stealth
  • combat
  • warmer/colder
  • classic sonic
  • modern sonic
  • dreamcast sonic
  • time trial
  • 3rd person shooter
  • flight

for speed type gameplay characters can choose between classic sonic which is 2d sidescrolling gameplay modern sonic which carries on the switch of 2d and 3d perspective of more recent titles like sonic unleashed or dreamcast sonic which is full 3d as to how it was in sonic adventure. The boost, spindash, lightspeed dash, and homing attack are availabe for all modes as upgrades but are optional if you want to use them or not. for hunter gameplay there is a choice of stealth which is basically getting to the goal undetected with very little need for hand to hand combat. Combat mode is basic hand to hand fighting between the enemies and characters. And there is also warmer colder, the gameplay which is used for knuckles and rouge in sonic adventure 2. the digging tool,strength power up and the glide ability but all are just upgrades like the speed characters. For lightweight characters there is time trial which is how tails used to play in Sa1 and 3rd person shooter akin to Tails gameplay in Sa2 and flight based on Tails ability of flight. Like speed characters there is spindash but there is also double jump and there is also the bounce attack. All the upgrades for every character are found in the hub world and can be used there. After the stage Tornado is completed there will also be a flying minigame similar to sky chase from SA1.

After sonic finishes the stage he is confronted by one of Eggman's bots called the Egg cobra. He defeats it. the trio show up at the bank inspecting the scene of the crime while knuckles jumps in. Sonic turns his head and is delighted to see one of his close friends. Knuckles examines the table that held the emerald and finds a shard of the emerald claiming that this is no ordinary emerald but this is the master emerald. But knuckles is confused as to why there is a shard of the master emerald here when he is guarding the master emerald on angel island. Knuckles is embarrased to think that the master emerald was stolen. The master emerald can act as a magnet to find the chaos emerald or the leftover master emerald shards if you just have one so knuckles sets off into the stage Twilight seaside. Knuckles finishes collecting the last pieces when he sees the shadow of a mysterious creature. Whats left behind is a claw and a ring. while he inspects it an explosion knocks him back. Its the water reaper. Knuckles having a fear of ghosts is petrified but then snaps out of it. He defeats it. Tails sonic and amy are discussing about the events that just happened and Knuckles enlightens them on the subject and gives the ring and the claw to tails and tries to inspect it. Straight away Tails recognises that this wasn't the work of Shadow or Rouge and it definetely couldn't have been Omega. He comes to the conclusion that there are new faces coming into the story. Amy thinks this new force could be working with Dr. Eggman. Amy thinks this because on tv it said that he was working with masterminds of stealth and speed to obtain the revival orb. Sonic and Tails looking for adventure decide to split up and locate Eggmans Head quarters where they can find out more about the new enemy/ies. Tails looks in Vivid palace.

It reads "All the truth all the lies i'll sacrifice to find peace all the lies all the truth ill keep to find the answers". Tails hangs on to the paper for more thorough investigation. As soon as they begin to escape the door shuts leaving Sonic annoyed but compliments Eggman saying he finally got something right. On the other hand Tails is petrified, when all of a sudden fists start pumping and the door shatters. It was Knuckles and Amy. He was searching for more shards of the chaos emeralds and as soon as he sees sonic he thrusts Amy over to him saying "Ive had it with her!". Knuckles starts his stage Egg trap. He escapes with more shards but he catches a glimpse of the silver chaos emerald he takes it aswell saying it could come in handy in the future. Tails sets off on his stage Workshop stop. Tails and Sonic are in Tails' workshop. He makes D.N.A match ups saying the that the D.N.A on the claw and the ring are the same. Knuckles comes in and throws the silver chaos emerald to Tails. He inspects the emerald saying that this was also a clear matchup. Seconds later an earthquake started. Sonic turned on the T.V and Dr. Eggman was on the screen with 3 others. He makes a death threat to the world saying that if he does not get the chaos emeralds in 2 days then he will shatter the earths core.

Team dark holding the last chaos emerald is walking into the shrine when the Shrine begins to crumble. Rouge asks what's going on and Shadow and Omega aren't so sure either. In teams sonic's scenario they're lying down near the entrance as well when the ground starts to shake. Sonic Tails Knuckles and Amy fall through the entrance. Sonic Knuckles Amy and Knuckles are outraged because they think Eggman still hasn't given up yet. Eggman revealed his master plan to team hero. He told Clawdia to steal the master emerald from angel island to send knuckles on a wild goose chase but she dropped a shard in the museum to make you think it was the master emerald being stolen but it was actually the green chaos emerald. Team hero is gobsmacked and their mouthes are gaping. Eggman outsmarted them all. Knuckles recovers from the stage of shock and starts clapping. Sonic slaps him on the head. On team razor's scenario they're about to leave as well when the ground starts to shake. They decide to go to the shrine when they see team dark in the shrine with the last chaos emerald. It's able to form the revival orb but when Team Sonic enters the shrine it breaks into 5 pieces. Team razor manages to enter the shrine. The pieces of the shrine are moving at an incredible speed and if they dont manage to stop it before it reaches the earth's core then it will shatter. The shrine's pieces teleport. Knuckles sees that the master emerald is also broken again. If they manage to meet up at one point then they can find and restore the master emerald and that has power strong enough to send the shrine back to its original state. Rouge says that it wont be easy. Sonic says that Knuckles told him before that emerald shards are magnetic. Then Eggman says that there are 5 hidden shortcuts in this shrine that he located. If everyone takes their shortcut then they can restore the shrine in time. Everyone sets out on their stage Doomsday crisis. Everyone manages to meet up. The master emerald is restored and the shrine is as well. Shadow sees the revival orb form and tells Greylock to make a wish because he earned it. Greylock wishes to resurrect his father. All of a sudden the Earh vibrates and Omega wonders why this is happning when they already restored the shrine. Greylock senses his Father. His body merged with the earth's core and is now destroying it. Everyone feels gravity getting weaker and they start to float. He summons Greylock and merges as well but he struggles to. Only his body merged and not his soul. Greylock manages to posess Shadow and Sonic to aid them while they turn into their super forms. This gives them the ability to switch forms from themselves and Greylock's powered up form Deathlock. His fangs grew 2 times larger and is able to rip them out and slice the air by using them as swords. This is the final battle between his dad and himself. It's restless and won't give up. Greylock understands that the reason his father is so angry is because he was reawakened and wanted to be left to rest. Greylock even though he is face to face with his father is losing memory of who he is. Tails figures out the meaning of the tatty piece of paper but he knows there is more to it. Rouge knows that her paper adds on to tails. Clawdia says that that poem was made by her father he knew what was going to happen. Tails knows that the only way to give rest to Greylock's father is if he goes to the realm of nothingness. Tails ponders upon this and realized that greylock was forgetting his father as he was brought out into the world. Tails knows that the realm of nothingness is the heart. greylock manages to use chaos control to teleport his father, but is growing weaker and passes out. Shadow and Sonic turn back to their normal forms. Shadow feels his pulse and confirms he is dead. Everyone mourns the loss. But he realizes that he and sonic have half of Greylock's soul in them and manage to transform into Deathlock again. Deathlock uses chaos control to revive himself. Everyone celebrates but shadow isn't, saying that there isnt much of the earths core left. everyone looks for the remaining pieces of the earth's core with only greylock shadow and sonic able to find them. everyone pitches in and uses ultimate chaos control to restore the earth's core. Shadow admits that sonic and greylock did a pretty good job to destroy the father of the underworld. did a pretty good job and each team parts from the shrine with eggman leaving in his egg mobile planning his next scheme. Greylock says that he has to remain as the guardian of the shrine so its power doesn't fall into the wrong hands. Clawdia and Scar support this and remain in the shrine for as long as they can live. As a true final boss if you collect all A ranks in each stage of the game you can see the very last cutscene. Dr Eggman still hasn't gotten his wish from the revival orb and is determined to get it and is now in the most deadly machine he has ever made the Egg demolition.
