The mod is pretty simple in that it fixes the weird Murkywater units found in evil bob's reskins. I've only really replaced the units with the Gensec Swat and created new textures for them.

The pack comes with a gray/navy green Murkywater uniform but it can be replaced with any skin for GenSec Swats and even skins for the FBI Swat including the ones found in the Murkywater Response Pack.

If you wanna do so, just replace the body texture "murkywater_df" in shared textures with the one you have (i.e. "swat_city_df) as well as ene_murkywater_1 and ene_murkywater_2 with the hat and helmet of your choice

The UMP-45 Gunner (ene_1) has a hat while the SCAR Gunner (ene_2) has a helmet

You're gonna need the original mod if it wasn't obvious
