4. Clive Barker's Undying (PC) - Snagging the Tibetan War Cannon
Clive Barker's Undying is overall a pretty terrifying game, pitting players against a wide array of cultists, monsters and undead horrors in suitably creepy ruins, crypts and English moors.

However, few things make you feel more at ease about fighting horrific beasts than having a big, powerful weapon at your disposal. That goes double if it's magic, and Undying gives you a big, powerful, magic gun so close to the beginning of the game that we wondered if it had been left lying around by mistake.

Above: BLIZZAM, BITCHES!

How are you supposed to be afraid of monsters when you've got a roaring, ice-breathing dragon head sticking out of your crotch? Anything that gets in front of you is going to be dust. Your ice-crotch will kill it dead.
