While I don’t really play scary games anymore, there are a few scary moments that have lived with me forever more.
One of them is the Butcher from Diablo. His terrifying “Fresh Meat” taunt was made even scarier by the random level design. Though he would only call out once a character entered his general vicinity, it was impossible to know where what the hell he was located. The rest of the level would see me inching along, trying desperately not to run away, but dreading the moment that the Butcher would ambush my character. This inevitable occurrence ALWAYS caught me by surprise, even though he announced himself from multiple screens away.
The other was the first Aliens Doom mod. The mod itself was fun, but the brilliant thing about it was that the entire first level was empty. I had no idea of course and was totally stressed out the entire level. Proof that my imagination is a thousand times scarier then anything anyone else can come up with.
