The chaps over at Half-life 2 done quick, a site which is dedicated to speed runs in Half-Life 2, have recently posted a video demonstrating that Ravenholm can be completed in 2:28 on hard difficulty.
You can find all the information you need right here.I made a new video showcasing a large amount of tricks possible in
Ravenholm to cut the completion time of the level to about 2.5 minutes
on hard difficulty. I edited them together and made it into a nice
downloadable file.
