I noticed that the Stimulus DLC Pack contains overgrown,crash,vacant,strike but how about other CoD 4 maps such as shipment,killhouse,wet work,downpour or countdown?

 

Does anyone knows where to find those maps or could any modder create one?

 

Any kind of assistance is welcome!!!!

 

PS.(I dont need to be lectured about spawnkillers and 60 people on killhouse ,( some maps are for small amount of people )

No, it isn't possible at this current moment in time.

Infinity Ward can do it due to them having the map tools.
