SWAT 3: Close Quarters Battle (also known as SWAT3 or SWAT3:CQB) is a tactical squad-based first-person shooter, developed by Sierra Northwest and published by Sierra Entertainment for Windows-based PCs on November 23, 1999. It is the seventh installment of the long-running Police Quest and SWAT series.
This is the COP Mod, A TC mod pack that "Overwrites" the game and brings a police quest style enhancement to Swat 3 along with more weapons and realistic police officers. (This file will not work when mods like Combat Situation or BBE Euro Forces is installed) This mod isn't by me, Nor do I take credit for anything inside, It was on the swat 3 reunited website and it was uploaded here to get interest in Swat 3 again.
Place the Cop Mod file in Sierra/Swat3/Mods, Enable via the swat 3 mod manager (making sure no other mods are on) and the mod will be ready to use.
