This is a speedrun of Office Complex (c1a2) in Half-Life, no using the elevator skip at beginning, the scientist skip a little later and the barney skip at the end. This was made to beat SuperFrizzio's time on this level with same handicaps. I succeeded.
This has been done single segment, all in one sitting using no save states or deaths. The best way to prove this is by looking at the single demo file (all links lower in description)
This has been done using the HLSPbunny mod and some scripts to bhop and object boost. The mod only brings back the old bhop possibilities, which have been patched in newer games. Using a older version of the game would have done the same result, but the demo support is better in newer versions, this is why the bunny mod is useful, it has the good demo support of newer versions and uncapped speed of older.
I know this isnt perfect, that's what you get with a single segment speedrun, which can never be as good as a segmented (asuming the same player runs)
The only video editing I made is removing loading screens (level transitions) and adding intro, outro and stopwatch.

SuperFrizzio's run: • Half-Life Office Complex without Scientist...
*You will need the HLSPbunny mod up to date (4.2r) in order to play the demo.
Make sure you create your own "bunny" folder in half-life, and extract the content of the .rar you downloaded in it.
