Chp1 Sonic Place: Wiskite's city'

-Eggman is gonna take over the city! Sonic's gotta stop him once again. While searching for any secret Eggman bases, a demon/shapesfiter captures him and Sonic becames (Exe).

Chp2 Tails Place: Green Hill zone-Hide and seek act 2

-Tails is going to Wiskite's city, but something makes the Tornado crash in Green Hill. Tails calls Sonic for help, he suggests to use the Cave connected to the city. After a bit of walking, Tails is in the cave and (Exe) is there too! Now Tails and the Exe gotta play Hide and Seek. There are 2 possible outcomes now:

1. Exe wins and Tails dies

2. Tails runs away but gets found in the city?

Chp3 Knuckles Place: Chemical plant

-Knuckles is visiting the abandoned Chemical plant to see if there's something he can use for himself. Unlike Sonic 2, the zone is empty and with lots of areas locked. Meanwhile, Knuckles is going around and the Exe traps him an area.

[I ran out of ideas. The other characters will be added in the next post when I get my inspiration back, sorry :( ]
