The picture below shows us a special HQ 18 defense base layout, the speciality is that you can hardly find where the Shield Generator is. Players of HQ 19 or above can find the position of Shield Generator with the help of Critters easilay, but players of HQ 18 or below have no way to find the exact position of it. Moreover, this HQ 18 beaching defense base layout can help you defense Warriors and T-med effectively.
Detailed Information of HQ 18 base:
1. Place Cannons and Boom Cannons evenly around the Headquarter. These are mainly used to defense Tanks. And the level of Cannons and Boom Cannons are the key.
2. Place Mines, Flame Thrower and Machine Gun around the Headquarter to defense the Warriors to rush to the Headquarter. This would do great pressure to Warriors Rush.
3. Beaching base is also the key to defense Scorcher. But this base is not good at defensing Scorcher-Tank and Heavies Rush.
As every coin has two sides, every base has its advantage and disadvantage. So you can use this HQ 18 defense base according to your own situation.
