Old church bells have begun to ring, once-occupied graves now lay empty, and never-before-seen creatures of the night have risen from their slumber for one sole purpose: to be shot!

A Halloween-inspired take on the traditional Mann vs Machine dynamic, Operation Hexadecimal Horrors features 48 brand new missions spread across more than 10 new, returning, and spookified maps! The campaign will run until November 30th, so don't wait! Servers are available in North America, South America, Europe, Asia, and Australia.

On an entirely different, less scary topic: a charity drive benefiting The Trevor Project will be running in tandem with the campaign. In-game medals are available for those who donate $5 or more! Check out the website to learn how to donate and how to play!
