Removing Units/Buildings as Buildable from Map
To Remove Superweapons (Or any unit or building) from the map load your map and open scripts. In the PlyrCivilian or neutral folder, make a new script and have these settings:
(Map->Modify->Adjust the tech tree for a specific object type)
Then Pick the name of the first unit/building and set the availability to "Buildable(No)"
Do this for each object for each general. To do it faster press copy and then hit edit on the copied action.
This will help you when you want to make infantry map only
