Mecha Green Hill Zone

Mecha Green Hill Zone is a level in Sonic.exe: Spirits of Hell and the final level of the Tails & Knuckles Duo Ending.

Appearance
Mecha Green Hill is a section of Green Hill Zone that has been mechanised and polluted by Dr. Robotnik. Most of the nature and flora is now artificial and yellow piping zigzags around the area. The water is polluted and full of oil, with giant totem poles floating in it, and a dam separates it from a polluted urban metropolis and tall, eroded mountains in the background. The sky is purple with the sun slowly beginning to rise.

In Round 1
Tails and Knuckles use the Master Emerald to teleport to the Zone after Knuckles says that he has a plan to purge Exeller from Sonic if he is standing still, and Tails suggests Mecha Green Hill as it has lots of distractions and gimmicks. Tails comments that Exeller will be here soon and asks what the plan is, and Knuckles explains that he is going to use a Chaos Emerald to obliterate Exeller. Knowing that the Emerald will protect Knuckles, the two run through the Zone to find a hiding spot, and the player can use C and V to swap between the two.

After clearing the first Act, Exeller will appear in front of the two and laugh out loud at their plan, before revealing a perfect red ring and throwing it at Knuckles. However, he ducks, causing it to hit Tails instead. The player must then clear a second Act, but this time Tails is under the effect of the red ring and it will not wear off. If he is caught by Illusion, the player will be sent to the Continue Screen. If they give up, Tails will die and Exeller will send Knuckles to Hydrocity Zone.

Once the Act is cleared, Tails will snap out of his trance and the two will reach a Super Ring. Exeller will scream "NOOOOOO!" and run at them, but falls over. Sonic will resist his control briefly and yell at Tails to run.


 * HELP SONIC (Wrong) - Tails runs to help Sonic, and Knuckles yells at Tails to listen to him. Exeller regains control and kills both of them.
 * RUN AWAY (Correct) - Tails apologises to Sonic before the two run into the Ring and warp to Mountain Peak.
