E-102 Gamma's Adventure

E-102 Gamma is the second newcomer to the Sonic series. He is an evil robot serving Eggman, who rebels and joins the light side. E-102’s adventure isn’t very long, and it’s pretty straightforward and simple. Basically in all the levels, just run around and shoot everything that you can see. E-102 also finds the Jet Booster, and Laser Blaster upgrades. 

E-102 Gamma’s Action Stages: 

  • Final Egg 
  • Emerald Coast 
  • Windy Valley 
  • Red Mountain 
  • Hot Shelter 


Final Egg

Final Egg is extremely easy, simply run along to the end to the Sonic doll. The only tough part can be getting the 50 rings for the second emblem. Before the checkpoint if you turn around there is a platform that you can glide to (once you get the upgrade to hover), where there are some rings. Also, right near the Sonic doll is a spring to launch you up to a platform for even more rings. 

Final Egg Objectives:

C: Destroy the Sonic doll. 

B: Destroy the Sonic doll with at least 50 rings. 

A: Destroy the Sonic doll in over the specified time. 

Final Egg Strategy: 

As with the level in general, getting the A emblem is very easy. Just shoot all the targets. 


Emerald Coast

After Final Egg, you will be tested by having to fight E-101 Beta. Just shoot him to end the battle, and afterwards you will arrive in Station Square. Head to the Emerald Coast area and shoot down the barricade to enter. 

Emerald Cost Objectives: 

C: Find Froggy. 

B: Collect at least 50 rings and find Froggy. 

A: Find Froggy is over the specified time. 

Emerald Coast Strategy: 

There are plenty of rings in the level, so getting 50 is no problem. Toward the end, you can jump up on the platform where Froggy is without having to follow the path around. That will shave some time off your score. 


Windy Valley

When you complete Emerald Coast there will be a series of cut-scenes after which you will be able to get the Jet Booster in Egg Carrier. After that, E-102 will need to fight Sonic (where before you controlled Sonic battling E-102). When the battle is over, you can find the Laser Blaster in Egg Carrier before continuing on. 

Again, us the Wind Stone at Tails Workshop to unlock the entrance to Windy Valley. 

Windy Valley Objectives: 

C: Defeat E-103 Delta 

B: Defeat E-103 Delta with 50 or more rings. 

A: Defeat E-103 Delta within the correct time period. 

Windy Valley Strategy: 

The long caterpillar-like enemies can net you a large sum of time points. Each section can be locked on as an enemy, thus giving you massive time if you lock onto the whole thing. Those would be the best source of time for you in this level as they can count as up to ten enemies. 

As for E-103 Delta, he is easy to defeat (as are all the robots) simply target him and shoot. 


Red Mountain

After Windy Valley, head to the Red Mountain area of Mystic Ruins. To get into Red Mountain is easy for E-102. Simply shoot the monkey to open the gate. 

Red Mountain Objectives: 

C: Defeat E-104 Epsilon 

B: Defeat E-104 Epsilon with 50 or more rings. 

A: Defeat E-104 Epsilon within the correct time period. 

Red Mountain Strategy: 

The same tricks that you used in the previous levels can be applied here. Just shoot every enemy you see. Toward the beginning are quite a few flying enemies and evil monkeys to blow up. Again, the more you lock onto, the more time you will receive. 

At the end of the level, E-104 Epsilon will be waiting for you. This robot will try to throw a little more offense at you, but he is once again easily defeated. 


Hot Shelter

When you complete Red Mountain, head to the pyramid area of Mystic Ruins and go to the Egg Carrier crash site. 

Hot Shelter Objectives: 

C: Defeat E-105 Zeta 

B: Defeat E-105 Zeta with 50 or more rings. 

A: Defeat E-105 Zeta within the correct time period. 

Hot Shelter Strategy: 

This is one of the only levels that can actually be pretty tough for E-102. The level is pretty long, which means you really need to get most, if not all, of the enemies in the level. 

When you get to the train part, you don’t have to wait for the train to stop moving in order to jump to the next car. Also, there are a lot of little monkeys on the train that you can blast for some time. 

E-105 Zeta is different than the other robots. To defeat him, you need to destroy the cannons around his "head". Just lock onto all of them and fire. 

When Zeta is defeated, you will have completed Hot Shelter. To get to the final battle, head to the large green area where the other characters fought Chaos 6. There, E-102 will immediately start the final fight with E-101 mk II.

E-101 mk II can be rather difficult, but his pattern is easy to learn. When he fires missiles at you, and lock onto them and destroy them. Then dodge out of the way when he flies at you, and then shoot him in the back. Repeat that pattern (while dodging his laser blasts) and he will be defeated. When that is done, you will have completed E-102 Gamma’s adventure, but not the game!

If you've beaten every character's quest, you'll unlock this bad boy.
