⚠ Obvious SPOILER WARNING ⚠
This shows parts of the end of Black Mesa
Here we go! Beat the entire game with both the hat and the pizza, without cheats. After my previous video on the incredibly tough 8 jump pads skip, here's the remaining hurdles I had to figure out until reaching the end game.

Some details about the tricks shown here:
The air vents only have a trigger area for shoving you at their very entrance. This is why I can go back into them to recover the items.
The elevator ride is a bit of a mess. Entering through the top skips a trigger that closes the "hidey hole" I jumped from. This is important so we can retrieve the other item later. The armor seems to stop the red lasers from being an insta-kill, which is nice.
Portal navigation wasn't anything special, but I included it since it was like an epic lead up.
