How do you get the unknown cheat and what is it?

That thing warps your wrench into a super ninja double-bladed thing. Really cool. It should be somewhere in the cheats section.

If you go to the cheat page or just scroll down this page you'll see the cheat code for it. This is the only cheat you can't unlock with skill points. It replaces your rench with a pink, double sided life saver that has much better range (if you have the upgrade for your rench that alows you to break stuff from far away, it will work on the cheat to).

I forgot how you do the cheat but I will tell you what it is it's a double bladed laser sword.

Oh, the one that you don't get by skill points? You get it by imputting a cheat that is in the cheats menue on this site.

To do that press o [] o [] ^ / ^ / < <

Just use, circle, square, circle, square up down left right while the game is paused

Its just a REALLY SUPER COOL DOUBLE NINJA BLADE SWORD) ok pause the game and enter:circle square circle square up down left left (TRUST ME ON THAT CHEAT IT WORKS)

It is the double bladed laser sword. Just use this code:

Circle square circle square up down left left(on the pause menu)

It turns your Wrench into a Purple Double Lightsaber from Star wars, it has a longer range, and looks awesomer. The code for it is Circle, Square, Circle, Square, Up, Down, Left, Left, it can only be done when the game is paused. When it is entered correctly instead of a sound, the pause menu will close and you will have the double lightsaber. You can turn it on and off from the cheat menu. I hope this helps, even though there is a lot of other answers that are helpful, I am just being specific.
