Westopolis is a city level in Shadow the Hedgehog.
Westopolis is a big city in the United Federation, that is among others such as Emerald Town, Central City and Station Square. Shadow is standing next to a tree in Westopolis relaxing and thinking about his past, and from the sky fall the Black Arms. Shadow, after a meeting with Black Doom, decides to go to Westopolis. Then, you choose whether you protect Westopolis, take out GUN or flee. The only enemies are the foot soldiers and flying ones, that is, GUN soldiers, Beetles, Black Warriors and Black Wings.
- Hero: Help Sonic the Hedgehog kill 45 Black Arms.
- Neutral: Collect 2/7 Chaos Emeralds.
- Evil: Follow the orders of Black Doom by killing the GUN soldiers and destroying their machinery.
Another area of Westopolis is Lethal Highway, and it is apparently where the Black Arms struck first because there is Red Slime everywhere. It is your choice to destroy their Black Tank or flee for good.
