Alien vs Predator gave me some of the biggest jumps of my gaming life, aliens appearing out of nowhere and all you hear is the loud screech as they attack from above and behind, or the little facehuggers, who you can't see cus it's dark, and then everything is silent...then you look on the floor...what is that? is that a ....oh ****! And then it's on your face and stuff. Spooky.
The biggest scare i got in Unreal 1 was actually kinda dumb now that i realize it, it was a one and a bazillion shot. I was in Chizra water temple, i had heard a slith sound and procedded to launch 8 ball rockets at it till it went away. When everything went quiet, i walked over to some health and some items. I began to collect, and then I turned around and the Slith i thought i had just killed (or it could have been his buddy, I didnt have time to ask) was standing right infront of me! Like and inch away, all i saw on the screen was the green bastard as it screamed at me just as I saw it. Man oh man, I remember jumping from my chair as I killed the thing, not before it got a good swipe at me. I dun remember, but my brother who was watching was laughing uncontrollably because, according to him, I had yelled out "Fu<k!" like a frightened school girl. Give me pupae and Skaarj, I'll pass on the slith thank you very much.
