The downside to this is that the buildings on the edge are completely undefended, so if the enemy spots them first, you may be in trouble as they will need just one weak unit to take each one out.Note: You can use this in conjunction with other base layouts.
They will be expecting the third-star to unlock when they destroy your HQ, only to find that there are more buildings at the edge of the area! If you put resource structures out there it means you are unlikely to lose your entire stash. Diversionary A good way to stop the enemy from earning a three-star victory (which is enabled when they destroy all of your structures), is to place some buildings on the extremities of the map.
