creepiest level in years (spoilers)

i guess the "lowlife" chapter was the creepiest level video-game level in years (even scarier than hl2's ravenholm level)... and that includes some survival horrors as well. for me, besides the pitch black and the constant antlion attacks, the scariest part was right after i re-enabled the elevator and had to come back to it... i just froze and wanted to stay in a corner to finish off the swarming zombies. when i noticed they were just too many, i sprinted towards the elevator, but for some unknown reason, alyx would not start it (either she was still busy fighting zombies, or i was too scared to put the flashlight on the elevator)... i was still scared when i got into the elevator, and as it was going up, i was afraid it would halt again.
good job valve for making a game with an attitude... pure survival horror.
