Have you successfully installed Sewer Run 2 via a safe method? Share your experience in the comments below (but please no piracy links).
Some sites like APKMirror (owned by Illogical Robot LLC) verify app signatures. Search for “Sewer Run 2 APK” only on APKMirror. Install manually. This is legal if the app is free on Google Play. However, APKMirror does not host paid apps for free.
Follow the developer on social media. Often, mobile games become temporarily free or offer their “full version unlock” as a limited-time promo.
Check the box that says "Run this program as an administrator."
