In Pulse, the 'monsters' can be blocked from a room by covering all the cracks and entry points with red duct tape. There's some half-assed explanation that it's because red 'blocks part of the spectrum they need in order to transfer'.
Also, the monsters 'get' you by touching and/or getting right up in your face and essentially sucking your soul out.
So, here's my question.
Why wouldn't wrapping yourself in red duct tape and/or getting into red clothing and/or painting your skin work? More mobile, more practical, and it'll get you into the damned computer room long enough to deliver the virus that will shut down the system and at least keep them from traveling via all the computer stuff they're using as entry points.
And if you get jumped? Close your eyes, cover your ears, mouth and nose until you can run from them (because apparently if you keep your wits well enough to run the process doesn't complete and you can escape).
So...yeah. Um. What did I miss? Because this seems to be a really easy obstacle to overcome.
