Advanced Crosslinking

Selena: Conway, I found a way to cross-link wires without needing a circuit box. I'm going to text you an address. Meet me there immediately. Don't let anyone follow you.

Conway: Selena? You're alive?

Selena: I'll explain later. Just meet me at this abandoned house tonight.

Later at the basement of the abandoned house:

Selena: Did anyone see you coming here?

Conway: Uhm, maybe. I think I saw a couple of guys in black suits...

Selena: Sh** you must take them down when you leave. Don't let this secret fall into the wrong hands.

Conway: What exactly is this secret?

Selena: I'm glad you asked...(Note: this could be a platform-specific bug-- I'm on Linux-- so I can't promise consistent results for everyone.)

Here's the trick: In the built-in level editor, It's possible to assign two colors to a single electrical component. So you can have a switch that can be connected to either green or blue.

Now PointEdit allows you to assign red to an electrical component (red circuit color isn't available in the built-in editor). Let's say you assigned yellow and red color to a switch. You can now wire this switch to any yellow-colored electrical item even if you don't have full control of the yellow circuit yet-- you'll need a yellow circuit box for that.

What's weird is that these two-colored switches expose a glitch in the game that will let you take control of the yellow circuit *without* needing to activate a circuit box!

Try it in this level-- at the basement, there are 4 switches each of different color-- plus red. They are all connected to the light in that room. Go into cross-link mode and verify that you *can't* control any of the circuits yet, except the red ones.

Now hit the blue-red switch. Disconnect it from the light, then hit it again. Check cross-link mode, and you'll see that you now have control over the blue circuit. Repeat this process for the other switches--- Hit the switch while connected to something, disconnect it and hit it again. Voila! You can now rewire that circuit color.

Let me know if you get the same results on different platforms.
