First of all, i must note again that the 3rd Demo will be a multi map singleplayer experience of Cod4 Rooftops. All Demos will leave the mystery of How we got on the Rooftop Map. How is the player spawn position on map "Rooftops" explained. Why were we trapped and prisoned ? All those questions will be answered in the Final Release Hopefully comming on Summer 2015.
The 3rd Demo will have 3 Maps.
-Map2: Demo preperation 65% Done
-Map3: Demo preperation 95% Done
-Map4: Demo preperation 70%% Done
So you its in good state.
