Okay. Imagine a horror shooter in which you are a grunt sent in with a team of other normal grunts to investigate a perfectly normal power outage at your perfectly normal barracks. That's right, no super soldiers, no spec ops, you're just run of the mill soldiers, only just nearing the end of your training. Hell, the only reason they sent you is that seurity requires you to bring a team, "just in case" someone was trying to get in.
Anyway, you get your normal squad commands, attack, take cover, follow me, stop. All on the d-pad. The sweep goes fine, and you get the power back on, until, due to another power outage in one room, you become seperated. You can hear your squadmates, but you can't find them. You go around a corner, and are struck cold by a monstrous apparition. It's claws red with blood, it's teeth countless. It walks towards you slowly. You try to get back round the corner, but the door has shut, and it won't open. You call for your squad to regroup. Nothing happens. Your character says nothing. You hear your men on the radio still wondering where you are. You try again, still nothing. Again, nothing. The creature gets closer, and you open fire. The shots make no sound, and deal no damage. You realise, you simply can't call for help. You want to, you need to, but you can't.
And then you wake up, on a plane with your buddies. It was all just a dream, the classic nightmare of not being able to scream when you desperately need to. You are headed for a perfectly normal base in afghanistan, where a perfectly normal communications error has occured...
Just for future reference, your buddies would not last longer than the first level. I played jericho, I know having a squad in a horror game is an awful idea...
