Half-Life 25th Anniversary Replay

I made it most of the way through without looking anything up which means I'm definitely missing stuff, but once I got to Xen I couldn't figure out what I was supposed to be doing several times. I think I'm two sections away from beating the game.

I keep telling myself I'm going to give Flick Stick a try and then don't do it at all. This is the second retro shooter I've installed specifically to give it a try and then I get into the game and start running around and don't do it.
