if you are on version 0.7 you must get the manual in the bunker it will show you the materials needed to craft Omega Kurfus. a new ingredient is the radioactive capsule which is located in a brown patch of dirt directly west from Satellite Q you must use a shovel to dig it up but be careful you can die if you are too close to it so either buy a radiation suit or get it last as it will kill you slower if it's in your inventory.

you will have to buy at least 2 normal Kerfus to get the required number of parts. 

in order to get into the bunker you need a hook to grab the keycard from the small window at the back of the bunker and a password changer to open the second door the book is in the far back right corner behind some creates. 

I have all the materials on the table, but whenever i try to craft it, it just makes the electronic scrap into drives instead of making kerfur. am i doing something wrong?? i don't have the hazmat suit and i'm on day 7 if that changes anything
