/cgl/ - Cosplay & EGL

I am planning the game version of Pyramid Head and while I don't think I'll have any actual construction problems, the vision in the helmet is a bit... problematic. After some time on google I found out that using a camera for vision would be an option but how viable would that actually be for a whole con day? Does anyone have any experience with anything like this?

I'd rather avoid cutting a hole and using mesh for visibility if I can but I'm a bit stumped since I've never had to think of anything like this with my past projects... Thanks in advance for any ideas!
