It’s worth watching the previous Half Life 1 speedruns as the tricks that are done in them could help us in Source. Also if you haven’t watched Waffle’s yet then DO IT NAO! 
“First off, I have to give credit to -think.circle- and Dopefish…”
Both of those people did runs. That makes 4 runs that we can draw routes and tricks from for our speedrun.
Spider Waffle’s
RandomEngy’s
-think.circle-
Dopefish
This would be the second time that we haven’t had to make as many route discoveries as the sourceruns team. :-[ Don’t wanna make that a habit but we should use these resources since we have them.
Ya, all previous runs have something good in them.

Wouldn’t put it past Spider Waffle if there wasn’t something in his single segment we could use as well. That makes 5.
