* HilariousInHindsight: One RunningGag is the complete absence of {{Dracula}} after the ''Franchise/{{Castlevania}}''-inspired Creature of Chaos map was added, starting with a gravestone in said map poking fun at his exclusion.

** The flame-throwing ''{{VideoGame/Strife}}'' robots from the "They Were Robots" spawn have the highest DPS of any non-boss, and one shot of their flame can kill you at full health.
