Hey there,
I am a Half-Life 1 speedrunner. After having a look at a lot of the Tech that is necessary for speedrunning Half-Life, I've decided to make some maps specifically for speedrunning Half-Life myself. Atm this project is kind of still in development. But one of the ideas that derived from my efforts was to archive and document the basic Speedtech necessary to master the Half-Life Main Campaign. I've put up a tutorial that is designed not only for advanced runners to reconsider the Speedtech to improve their runs for HL, but also for Mappers to give an idea about what might be possible to explore in Mapping.
I'd like to encourage mappers to think more about how amazing Half-Life is for speedrunning purposes. Have a look at what you might be able to put into maps to provide what Half-Life holds as one of the unique games created for gameplay possibilities.

I've decided not to put up another vid for this again atm because all the necessary information are explained in the commentary and easily accessible via having a look at decompiled HL Main Campaign maps yourself.
Be invited to step forward, create maps or even mods, also if they are only created on (the pure) HL main campaign physics to give us something to run, explore the game, and advance in difficulty levels to reach the limits of HL potential. I'm pretty positive, there are not that many games anymore providing players with either the phyiscs nor the simplicity of mapping worlds for a game as HL does.
Also have a look at our leaderboards (for practical action and inspiration).
