Help for the game "Cryostasis"

Hank_Scorpio

This is a pretty random request but I'm desperate for a solution. I make game trailers for fun every now and then, and I have some ideas for a Cryostasis video, but I need to find a way to disable the HUD to do it. I haven't been able to find any way online, and I was hoping that maybe somebody here knows a way. Thanks.
