|Description||Kill all three guards and complete Vengeance level 6 (Nightmare)|
|Orb Points||300||Orb Coins||3|
It is not enough just to lure each one of the three guards and kill them individually at a generator. If all three generators are destroyed, you will die ten seconds later, making it impossible to finish the level. At least 2 of the guards must be killed at a generator simultaneously. The second and third guards are easier to kill together because they are closer to each other.
