Allright, So first, Download WPEPro. It will come up as a virus, But it is a false positive, It sniffs and edits packets, Which is what viruses do.
Target robocraft, And then, Go to View>Options and untick everything but SEND.
Next, Join a battle, As soon as the countdown for the match stops, Click the little arrow to start recording in the top left corner.
You need to get a kill in the match for it to work, Or atleast damage enough enemy CPU.
Click the square for stop.
Now, A little window will pop up, Scroll down until you see something along the lines of "Cubes destroyed award"
Right click that, Hit send, Another window will pop up, Set the interval to 100 Milliseconds, Make sure it is on continuously, And just start it. After you hit around 9,000, Re enter a battle and then self destruct without doing anything. You should see your level go up by like 20-40 depending on your starting level.
Cheers!
