i downloaded the new dlc and installed it and i dont know how to start playing the new chaos mode

i tried launching iw5sp but it said "this game is currently unavailable"

SP is and will not be supported.

SP support comes from Steam, not FourDeltaOne

Really,always wondering why doesn't 4D1 support sp?

Because it doesn't.

Prolly to avoid as much unwanted attention as possible

Buy I W 5 from Steam

i have it on steam but after i installed fd1 on it then singleplayer stopped working

But 4d1 doesn't touch sp files

if any one need special ops or chaos mode use teknogods.exe its work sp 100% all new and old maps
