I found a 175 blueprint (acsendant) that was wicked awesome, but it cost 4000 metal ingots, 10000 element dust, 500 oil, 2500 crystal, and 3000 polymer. Am currently farming resources for it, afraid I may never make it.
For a basic enforcer, go around the city and gather at least 500 element dust from lampposts(preferably more), kill a few isolated enforcers until you get 20 oil, go to the wasteland killing the weaker corrupted creatures for corrupted nodules (they can be used as polymer)
When you collect all the resources, go to a city terminal and craft your own enforcer.
The Enforcer drops a blueprint upon being killed and the blueprint dropped will give you that exact enforcer you just deafeated. It will have the same color(s) and stats as the one you killed and can be crafted at any city terminal. The higher the stats the more ingredients you will need.
In extinction, you can kill some of the defense units, then if you go into the badlands you find this small thing that allows you to build one, if you have enough resources, the more leveled up they are, the more they can teleport, The most teleport things they can have is five, but can reload within seconds
Trust me when i say this, its easier to make a level one at a terminal than ti make the 180's and crap. Best way to level up is to mount next to a explorer note and get next to it, since it'll get the xp boost too. Then fight corrupted dinos, because enforcers and defense units do 2× to 4× damage on corrupted dinos.
To the guy that had an enforcer with all them wild resources, I also got one. A level 174 enforcer. I built it up, until its level was 288. It had 50000 hp and did around 5000 damage to corrupt dinos. Then i fought the king titan on gamma, but ark glitched and it had the alpha stats. So, it 1 shot all my dinos, all my alpha titans, and a space whale from gen 2. This includes my poor enforcer, who’s blueprint fell through the map. Jarn, you’ll surely be missed.
To get a blue print of an enforcer your will need to kill one and got to it's inventory and collect the blue print (the higher the level does not mean you could always get a good blue print but I'm not fully sure!) You will need metal ingot,oil,element dust/normal element etc
