Open the file defaults.ini file in the main dir with a normal editor
 and look for

 developer_mode = 0

 and change it to

 developer_mode = 1

 Then open the file default.ini in the /configs folder and look for the
 cheat key section and add these lines:

 [icPlayerPilot.DevIndestructable]
 Keyboard, I, CTRL, ALT

 [icPlayerPilot.DevKillCurrentTarget]
 Keyboard, X, CTRL, ALT

 [icPlayerPilot.DevJumpToCurrentTarget]
 Keyboard, G, CTRL, ALT

 [icPlayerPilot.DevDamageSelf]
 Keyboard, K, CTRL, ALT

 Save and start the game. You now have 3-keys-combinations with the
 corresponding effect. Please use this carefully, espaecially the
 destroyer thing.
