Some of the best terrifying moments come in games which, otherwise, aren't particularly scary at all. For the majority of Half-Life 2 the threat is the constant attacks from Combine soldiers and the firefights that ensue, as opposed to the steady pace and ratcheting tension of a horror title. Once again, that just makes the appearance of a down the line terrifying sequence that drops into the game about halfway through - just long enough for players to have gotten their bearings, not long enough for them to have grown complacent; lulled into a false sense of security, maybe - all the more petrifying.. Your mute ex-Black Mesa scientist Gordon Freeman is left to his own devices after being split up from comrade Alyx, meaning Ravenholm is one of the few sections of Half-Life 2 where you're actually alone. Well, you'll wish that you were alone. That way you wouldn't be creeping through an abandoned town whilst a David Lynch-style industrial soundscape claws at the fraying tethers of your sanity, jumping at every noise whilst you try your best to make your way to the other side of the Headcrab-infested environment. Your HEV suit won't save if you if you wet your pants but, really, nobody would blame you for feeling a little bit terrified when you go to Ravenholm.
