[@Kron27j]

Would probably take too long, i bet many stunts here take plenty of attempts. Heck, i'd be impressed if he can actually complete the game. But quadra (and the HL21 team in general) have surprised me before Edit: he already claimed in the description that this is ends at the first "impossible" scenario, so he might twinker around with console commands for those parts.

[@itsFODDER]

Doctor Corn It's unfortunately impossible. Especially due to the outside maps later in the game. At least from what quad told me.

[@Kron27j]

I imagined as much, but thought he, or someone else, might do some map editing as a last resort to turn the impossible ones into just a huge (possible) challenge. That's pretty unlikely and probably a waste of time, but the idea sounds cool, great video anyways even if he didn't continue the series.

I realized by the first minute that you were actually playing the game upside down, not just flipping the screen. This is amazing! :D

[@MaverickJeyKidding]

Why Half-Life is revolutionary game you may ask? I say - because it's content offers endless posibilites for gameplay researching. In all ways. In any direction of applying. Can you tell me Valve planned maps geometry so good that they knew one day HL is going to be played upside-down? I won't believe you. Look at this, it's as if everything was planned and tested YEARS before releasing the actuall game. And that run is not the only example. Even to this days we still discover new planes and edges of that "func_halflife" brush. Who knows how many are there yet to be discovered. Maps, sprites, sounds, models, source code, console commands. This is the definition of an interactive game that is full of bugs, yet doesn't crash no matter what.

Also, now that I realize, and since I'm on a great mood today to feel like pointing it out, good job on that _Argument from ignorance_ fallacy, the extra _ad hominem_ was a nice touch, too. *You: VAC [has to do with the issue.]* You assert that VAC is brotalnia 's problem, yet provide no proof. *YaLTeR: What does VAC have to do with this?* He asks for proof. *You: You tell me, Brony*
