I can't remember, I swear too much (don't like it) for too long now. However, I do remember the most noticable swearing-at-a-game incident.
It was FEAR, and I was playing the office level with those stealthy melee baddies. The whole level just builds up the tension before you encounter them to scare the living crap out of you, they managed that, but the real moment came a little bit later. I finally figured out how to spot them (you hear this distinct sound when they decloak, then slow time, turn around and pump them full of lead) but I was still low on health (yay for higher difficulties, yeah I tend to start shooters on High). But after a running frantically around for a while, killing a ninja thing and almost killing another (bastard got away) I suddenly spot a medipack in one of the few safe rooms. So I quickly dash towards it, and ríght when I enter the room and grab the medipack, a ninja decloaks in the top right corner of the room, and I'm staring right in his glowing little eyes. I shouted the loudest "goddamnit!" I ever shouted, almost fell out of my chair so high I jumped from it.
