Warning! Here be spoilers.
Juggling and doing a backflip
I can’t say that I didn’t attempt to juggle the first time around, but I did it so poorly that I gave up after a minute. ChrisQuitsReality has already been covered on RPS, but he’s released an improved follow-up to that. I’m still too scared to do half this stuff, even with a nice amount of space in my room, and he goes and does a backflip…
Using a barrel to corral headcrabs
This video by Bed Bananas is full of things. It starts off making you think he’s a gaming god, somehow managing to plow through a Combine assault like Neo and John Wick combined into a single human being (as if that’s possible). But things quickly devolve into panicked chair swinging, creative use of barrels, and a loving and caring relationship with an entirely alive partner.
Tossing keycards like Ricky Jay
I… I think I can do some of these? DefendTheHouse’s trick shots are definitely possible. I don’t think I have the patience to carefully set up suitcase dominoes, but I can huck a keycard for sure.
And to think that my original plan was to carry the gnome all through the game.
