I'm at the point where I'm building the gloves and for that I need the special alloy the only one mentioning it is the engineer and he says I have to talk to archie. But who and where is archie
Going into the factory, click on the sign that has a red arrow going to the left.
After that, you first talk to the light blue robot, then talk to Archie, & finally talk to the robot again to get alloy.
