Hi all I would like to try and do speed running on portal I have the steam version of the game manage to do some of the glitches save glitch doesn't seem to work in chamber for not sure why not sure how to get on the leaderboards and would like any other helpful advice to make my speed running time better thanks

First off, don't use the steam version. Go to the resource page and download source unpack, this is a file that contains hl2 and portal before any glitches were patchted out. as for getting on the leaderboard, on the leaderboards you'll see a button labeled "submit run" click that and then fill out the page (things like time with and without loads, what category, if you used vault save, and provide the YT link to your run). And some helpful advice, I recommend having a in-game time timer and real time timer on livesplit. Also I recommend you watch XeiZ SC, he has the best tutorials for any strat (in my opinion)
