Im stuck in the black vulkar base, have ( i think) killed everyone. but i need a pass it says to getinto the engine lab ot get the prototype. thats the only place i cant get to. i can get into the loading dock ( the only other locked place).

any ideas?

Go back up to the top floor of their base, kill everything you see, then work your way down, searching absolutely everything that can be searched. It’s there somewhere.

There’s a key card at the other end of the hallway.
