Allows playing the 4 EU maps which are not avaliable in EWI:
URB_Museum, URB_Museum_Euro, URB_Demolition, URB_GasStation

Currently the script works only on Windows
The patches are not perfect, some of the textures will be missing, others will become black at close range (unless you set texture quality to minimum)
Applyable to XCom vanilla and Longwar
