Expert+++ (E+++), also called “Expert++ 2x Alarm”, is an unofficial game difficulty setting which can be played using Custom settings. It is the same as Expert++ mode except that the alarm tracker rises twice as fast in all circumstances.

To play on Expert+++ mode, start with the settings from Expert Plus mode (or Endless Plus mode), select “show settings”, and make the following changes:

• 0 starting PWR.
• 0.5 credit multiplier.
• -1 KO time.
• 2x alarm multiplier.
• 0 starting credits.
• “Less” Consoles per level.
• “Less” safes per level.
• “More” daemons.

Expert+++ was first introduced by Mozzy.
