Unless it changes in 0.13 the biters don't care if defenses are functional or not, they target and destroy them all the same.MeduSalem wrote: But that is something I want to try out with 0.13 again when there is something like sensors to spot the enemies. Then I would cut off power to the turrets as long as the biters aren't in the death zone so Biters ignore them and once they are lured inside, bring up all fire power from all sides. Pretty much like a trap.
I've actually exploited gun turrets without ammo to eliminate biters. If you place a gun turret on an island, then passing small biters will attempt to engage it (even if it has no ammo), the game then immediately deletes the small biter for targeting something it can't reach. It's a pretty good exploit because it simply deletes all small biters which attempt to pass by and since biters tend to follow coasts you can get maybe 70% defensive coverage with a few turrets with no ammo, at least until spitters evolve. I made a bug report and a dev said the AI is changed significantly in 0.13 so we'll see what happens.
