ENGINEERING PROGRESSION
The following list should help you decide which engineers you need to unlock for your particular build. My suggestion is to use Martuuk for G5: FSD then get to Tani next for the G5: Powerplant. The Dweller will build your G5 Distributor and give you access to Cheung for Shield Generators and Sensors. Get Palin as soon as possible to in order to have G5 Thrusters. The rest can be done at your own preference depending on your choice of weaponry, but having the above engineering will make a big quality of life improvement for you traveling from system to system gathering materials, trading, mining, running missions, etc. prior to building a combat ship.The RED highlighted upgrades are my suggestions for pinning at each engineer. Since you can only add experimental mods at the engineers shop, I suggest adding it during your first visit then pinning the mod so you can finish it as you gather the required materials.
