Labeled as UMR-S, this is a Modified version of the UMR Mod, that doesn't have the Squeak Through mod as a Required dependency, instead is optional.
It is recommended that you have some alternative method to travel over/between objects, such as a Jetpack, or Grapplehook.

Make sure to give Love to the original Mod Owner, and Mod Page!
