About the Rosenberg skip: The elevator works with any monster entity of the game (even in dead state) beside the weapon ones. With a bit of messing around the map, shrimp found that you can get an headcrab through the wall using 20 fps and satchels, since the command for fps in a dedicated server doesn’t really work like in local cause you’re hosting with a dedicated and not with your client, we used the "sys_ticrate" command which does the same things as fps in local (faster sink, faster npc’s movement, etc) it’s also capped in the same way - min: 20 - max: 200 - we used the values default 100 for the whole run and 20 for a few seconds just to get headcrab through. This skip can save up to ~5 minutes.
