Look, we're not gonna tell you how to spend your hard-earned money. If you want to spend two actual dollars enabling your Killzone: Shadow Fall character to fart -- yes, that kind of fart -- and "plank" (this) on PlayStation 4, go for it. But allow us this moment of plea: please don't. Here's the description of what your $2 gets you:
"It's all fun and games until someone loses a game. (Or so they say). Show your fallen enemies, not everything need [sic] be taken seriously. This pack contains Fart, Planking and Comedy spotlight moves."
One part of us wants to know what "Comedy spotlight moves" could possibly be given that the highly comedic farting and planking verbs have already been used.
