Sonic Adventure 4: Deadly Past is the fourth installment in the Sonic Adventure series. It takes place 2 years after the events of Sonic the Hedgehog 4: Episode II, and about 3 months after the events of Sonic Adventure 3: Rebirth. It was rated E 10+ for ages 10 and up because of the more realistic looking levels, and the deadly name.
The gameplay is simillar to Sonic Adventure 3: Rebirth and the other 2 Sonic Adventure installments. Each character can use certain moves to get past levels, defeat bosses, and the special stages! The special stages are sort of like the design of Sonic 2's halfpipe, execpt that robots will try to take your rings, and it isn't automatic running. You still have to collect rings to get the Chaos Emerald, but now Super forms can be used within the special stages or other areas after they collect all 7 Chaos Emeralds and beat the final boss.
- Sonic the Hedgehog/Super Sonic- A hero hedgehog that rushes by at supersonic speed! Rolling into a ball is his game, Sonic is his name.
