Loot Cave Easter Egg

The Loot Cave Easter Egg is an easter egg in Skywatch, Old Russia, Earth. In the monster cave in front of the large building, there is a pile of bones that can be activated to play a dialogue line: "A million deaths are not enough for Master Rahool." The line references the fact that players were able to farm engrams from killing monsters spawning in this cave prior to Hot Fix 5.

The line could also be a reference to Frank Herbert's Dune due to its similarity with the line: "A million deaths were not enough for Yueh!" Whether that reference was intended or not is unknown.
