Over three acts I have written a plot that I hope is not only fun, sensical, and well-paced, but also one that expands and explains various features of the Sonic Universe
Alien machines have begun appearing across the planet, wreaking havoc and capturing Mobians. It falls to Sonic to form a team and fight back the invaders!
*this act is mostly narratively linear
Act 2
Act 2: The Auto-Facs
Deliver a decisive blow to the enemy and destroy the alien-robot-factories. Explore Mobius and complete side-quests for upgrades, gear, and fun!
*this act is all open-world
Act 3
Act 3: The Seven Chaos
Can Robotnik and Metal Sonic be stopped? The race for the Chaos Emeralds is on!
*this act is mostly narratively linear
Act 4
Endgame and DLC
With Robotnik gone and Metal Sonic defeated, it's up to Sonic and friends to restore the Chaos energy to the planet
