Lookout Posts can be built in order to allow survivors to defend their colony better - by reducing awareness and thus the frequency and intensity of demon base assaults.
This is done by assigning survivors to patrol the towers.
- It's best to make lookout towers closer to the edge of the screen, and far away from each other.
- Fighters, Defenders and Scouts are naturally better at patrolling.
- The patrol skill can also improve patrolling.
