Updated the first post with whole Allied Coop Campaign, which was done together with Petya - there is also audio desync, because of the lags during play on CnCNet, Camtasia has got problems with synching video/audo. The coop missions are somewhat easier than the regular Single Player campaign, the only real hard mission is Blut Royale that demands decent micromanagement and teamwork from both players.
