Since I have 0 points in electronic I need the repair robot to open the doors to tchort. I can't really find how to find it's core, I know I need to take it from the arke power station (from what I've read). I think I have all the keycards and opened all the doors, while under it, where the electric spiders (thank Leo) and the electric floor are, I can't use the console (it keeps on blinking). There's also a small room with a console wrapped into the spiders' net and another switch. None of the other security console do anything. There are some power box and I've tried to turn them all off or on but it doens't change anything. The AI even stopped trolling me she must have seen my desperation :|
