Yo, sup. I feel like doing some voice acting for SFM works.
I am not a voice actor for one of the TF2 characters, I am what you might call a "Scary Movie Narrator". y'know the:
"In a world where stop means go, where chaos runs the streets...Mountainous Pain, coming to Theaters, July 23rd"

-------------EDIT--------------------
I just added background music for the full effect

this is an old post, might update it soon, but my current setup is an sl150 from editor keys with a pop filter.
