You know when you're playing Halo or Call of Duty with your mom, or dad, or a girlfriend (or boyfriend) who doesn't play video games and you're standing there and they just randomly shoot you as they come around the corner because they think you're a bad guy?
Yeah that's basically all of your soldiers in XCOM. They turn around randomly when panicked and shotgun the guy standing next to them. There's no sense to be made with this game's panic system. None at all.
