AAAH!
Gigantic wolf spider appears on wall next to me during wave 10, surrounded by geth. 
Thankfully it sits still (about a foot from my head), so manage to keep playing and take cover in safe corner of map - figure time out is 2 mins. Find cup, pout out water, catch spider in cup (it just fits!) - see pyro flaming down to a couple of bars of health... unfortunately didn't get back in time; had to burn a medigel. BUT IT WAS WORTH 1 MEDIGEL!
In my previous house, I used to play games and watch TV in the basement. So, I'm playing Halo 2 in a dark room, and I notice a human hand scuttling across the carpet out of the corner of my eye. I wasn't sure how any of the human hands could have escaped the freezer in the garage, so I take a look, and it's this big ol' spider that would require Samuel L. Jackson to describe properly.
By the time I'd switched out hollow points for FMJ rounds in the Glock (figured I'd need the extra penetration on the hairy little tank), the bastard had disappeared. I didn't start the game again until I'd set up a proper barricade.
Anyway, Google up Tegenaria Duellica for a look at my former roommate. They're nasty to look at directly, but they're a darn sign more unnerving out of the corner of your eye in a darkened room.
