As all of you should know COE mission disk can be installed as a standard Urban Operations Mod. Infact it's a stand-alone product, but if you have also RS and UO you'll be able to make COE work as a UO mod and doing this you'll be also able to use the other UO options like the mods folder. Then you'll be able to use COE missions both with the standard COE exe and as mod in UO.
