Best Lvl 5 HQ Base attacked by various combinations of troops and from different directions. This base design is very strong in that all important stuff are protected by the two shield generators (including HQ, resources, and turrets). In this video, four attacks are shown and the base survived without losing any stars. If you want to use this base layout, try to copy the first base attack (it is the latest with mortars near the center). This is version 1 of my level 5 base layout.
