(SPOILER: this conent may make your game too easy for few maps)

They way energy barriers works (every barrier automatically linked with other near barriers) allows to create a "perfect barrier".

All you need is a Narrow Passage in wich placing the barriers Then you create an half-circle to cap the passage, enemies will be inside the circle. Looking at the picture you can see that you can create a barrier that protect barriers projector making that virtually impenetrable.

I needed this kind of trick to win first Military maps, without that winning the first map is very hard while the second map is almost impossibile.
Unluckily that works only for narrow passages, you can't protect your base by surrounding it, you can only cap canyons.

Since advanced projects are expensive (1000 each) you can use advanced projectors in place of "RED" and more economic projectors in place of "green"


For each segment of red barrier then place 1 light to attract enemies in the middle of the barrier and 1/2 laser cannons for each light

(there are 2 projectors that are still unprotected, ideally put them behind rocks so that enemies can't destroy them)
