[x] Repairs and Command
In the end you decide to go with the shelter for you choice of foundation. It has the best defenses and doesn't hinder your ability to use either Terran technology or your own Zerg bioforms.
Still with all these terran defenses it's clear you're going to need something to repair them least combat or time wear them down.
At the moment you can see two options, you can try and have some of your infested terran pilot some "SCV's" you found in the shelter or you can and infested one of the automated construction machines you've found in the bunker, you're not really sure what the consequences for either would be, but you'll probably find out in due time.

Next you begin looking for a possible command strain, or at least a method to help ease the strain on your own mind for a bit.
The first and most simple option is to go track down some Overlords for their essence. It may take a bit of effort to hunt the overlords in question down but it should be worth it.
Secondly you grow some infested terrans the long way and have them lead their fellows. While you can't really replicate terran psychics at the moment this new strain should be relieve you of the need to focus on minor details, and allow you to spend more time of the bigger picture.
Another possibility would be to grow terrans the fast way, but attempt to combine them with the damaged overlord essence you managed to retain. The effects will be nearly unpredictable though.
Finally you can try and infest some of these 'computers' the terrans have in some of their structures, they won't be very smart and you'll need to add in some Overlord DNA so they can actually control things, but they should do the job well enough.
