Step 1: Kill an enemy and steal their guns
Step 2: Stand in a fire and burn their guns (and yourself too 😱)
Step 3: Spectate the enemy to watch how they react
Step 4: Profit
All credit goes to @Huuge for his strat in "The Most Evil Hunt Showdown Challenge Ever" video: • The Most Evil Hunt Showdown Challenge Ever... It is quite funny all the different possible ways people can react. I think I'd like to try to do it to a duo too, and also try it with a solo but instead of burning the guns just using push-to-talk instead.
Thanks to Cunning for being such a good sport! I sent him a message on Steam afterwards and I think he found it funny too :)
