A True Engineer (20)

Construct one of each craftable item

In order to craft an item, you must first find the blueprint for that item.

Once you have a blueprint, hold B to bring up the radial menu. Choose which item you want to craft with LB. From there you can see which materials are needed to craft a specific item. Once you have finished gathering and applying all necessary materials, press LB to craft the item.

There are seven craftable items altogether. You can find more versions of the blueprints throughout the game, each item has three different blueprints.

Prendi's collectibles guide details where you can find the blueprints (click here for a link).

I've listed the places where you can find the first version of each blueprint:

Medikit - Blueprint can be found in mission two, "Welcome to Sevastopol." You will have to crouch under a wire to avoid taking damage from electric discharge. At this point the blueprint will be on a bench, directly in front of you.

Smoke bomb - Blueprint can be found in mission three, "Encounters." Once you grab the revolver and continue past the door that required a keycard, make your way into the room with the two large metallic tables. The blueprint will be on the table closest to you when you step into the room.

Flashbang - Blueprint can be found in mission three, "Encounters." After getting the smoke bomb blueprint above, move right down a hallway towards the room with the dead body on the chair. Once in this room look to your right and the blueprint is on the wall.

Noisemaker - Blueprint can be found in mission four, "Seegson Communications." After heading up a set of stairs with a save station at the top, move past the next door and directly across the hallway will be a door with a brace on it. Remove the brace, continue through the door, move right, and the blueprint will be in a small lounge area on a table.

EMP mine - Blueprint can be found in mission four, "Seegson Communications." Once inside Internal Communications, head towards a save station that’s in a small side room in the back. Next to the save station is the blueprint of the EMP mine on a table.

Pipe bomb - Blueprint can be found in mission five, "The Quarantine." Eventually you will discover the location of Dr. Morley’s room on a whiteboard. When you see that, exit the room, turn right, go down the small set of stairs, and then head into the first door on your right. The blueprint will be on the table closest to you when entering the room.

Molotov - Blueprint can be found in mission six, "The Outbreak." This one is a little harder to describe compared to the others, but you will come to this area where there are two rooms directly next to each other. The room on the left has a locked door inside that requires a keycard, and the room on the right is labeled as the “security desk.” Head into the security desk room, it’s got a save station there. On the table is the blueprint. Watch out for the three traffic cones in the hallway outside. If you get too close to the cones, something will explode and fire will start spewing everywhere. The noise attracts the Xenomorph so be careful.

Also, if you have the Crew Expendable DLC, you can craft everything but the medikit and the EMP mine in Survivor mode. You won’t need blueprints to craft items in Survivor mode.

Dallas can make the smoke bomb, pipe bomb, and the Molotov.

Ellen can create a flashbang.

Parker can craft the noisemaker, flashbang, and the Molotov.
