On the PTS / Beta branch, one extra capability is enabled which isn't on the live build : the console. It allows you to use some cheats to help in testing.

To open the console, hit the "backquote/tilde" key (or where its located on the equivalent English keyboard layout).

Here's a list of known commands I've found useful at this point; just open the console and type or paste :

• servercommand fly
  
• servercommand god
  
• servercommand givexp
  
• servercommand givegold
  
• stat fps

If you find any other useful ones you'd like to see added here, fire away!
