T-Rex the Porcupine

T-Rex the Porcupine (T - レックス ヤマアラシ T - rekkusuyamaarashi), known in Europe as T-Rex Begins, is an action/adventure game Developed by Sonic Team and Published by SEGA.

Story
While exploring the Bayou Swamp, Sonic and his pal, Tails, encounter an unknown beast who seems awfully familier. Sonic and Tails stayed perfectly still and didn't say a word hoping that the beast will go away, but didn't. Sonic figures out that it dosen't wanna do any harm. He pets it, but suddenly several Eggman robots appeared, but the beast sweeped them all away quickly! Sonic thanks it for saving him and Tails. They later decide to take it home and experiment it, but the beast insists that it leads them out of the swamp. Suddenly the beast spoke! It said it's name is T-Rex the Porcupine, he is Sonic's long lost cousin. Sonic froze for awhile, so Tails carried him while shocked in awe. The tutorial begins from there.

Gameplay
The game consists of three stages, all for only T-Rex: The Action Stages are based on the Werehog Sonic combat system, with some changes, obviously.
 * Action Stage = Beat 'em Up
 * Speed Stage = Sonic series-based gameplay
 * Flight Stage = Shooter kind of game

The Speed Stages are traditional Sonic series gameplay, also with some changes.

The Flight Stages are similar to the Tornade gameplay, again, with changes.
