Alien vs predator... Ahh.. the memories...
About 10 - 11 years ago I had a copy of AvP2 and I played it with a friend. He was playing a marine in the solo mode and I was sitting next to him.
We were sitting in a darkened room as well and in the storyline mode we just lost contact with our team in the game and were on our own. He was walking around when the lights were going out and the creepy music and background noises started to play.
Well as you probably remember you have a radar with white dots on them when aliens are approaching. I was watching this radar closely and saw 2 dots appearing.
Me: Nick, I see 2 dots.
Nick: Ah don't worry, it's nothing.
:::He keeps on walking and we stand infront of a door.:::
Me: Nick, I really see 2 dots!
::: He opens the door. :::
*2 aliens jump through the door right in his face in the middle of the screen*
Me: NICK WATCH OUTTTTT!!!
Nick: AHHHH God Damn it Jasper!!
*He starts firing wildly while having an alien sitting on his face and killing him.*
I nearly gave him a heart attack that day and we still talk about it 10 years after that incident. When I say 'I see 2 dots' it's enough to make him say 'shut up'.
Funny thing is that he probably wouldn't have been scared shitless if he I didn't start yelling so much in his ear right behind him.
