Oh avengers. When they spot enemy they become all excited and start moving towards them :D I force fire to ground so they don't move and do what they are supposed to do: take down planes and intercept missiles :) Avengers are also useful when attacking: "When targets are painted, other units in the vicinity can fire faster and with better success at them."
It's actually a map made by players, with pre-set waves of enemies. You can download map here: pashacnc.com/mapmakers/MM_P/Twinsen/Twinsen.html (map name 'AOD Level Ups Final V5! By Twinsen'). Copy map folder to C&C "Maps". Usually it's located: My Documents/Command and Conquer Generals Zero Hour Data/Maps. When creating game: SELECT MAP - unofficial maps - and find it. Then players select armies and teams (up to 4 players) and one AI-hard army-GLA (see video 0:00). It's very important to put AI to correct position (nr. 5). To prevent game from crashing, all players should set video setting to custom: uncheck all boxes and set all slidebars to minimum. No point set it on high if game crashes mid game :) I hope this helps so you can set it & play :)
