Q: What are you trying to do?
A: Beat the game. Depending on category this can involve glitches.
Q: Isn't bhop a cheat?
A: In Portal Valve tried to fix Bunnyhopping, which created ABH. They actually fixed Bunnyhopping for the most part, which makes it "just" go to maximum allowed velocity for efficiently and more often than regular jumping. It also makes curves much easier!
Q: You just saved, reloaded and started shooting Portals in weird spots without them ever appearing. What sorcery?!
A: Saveglitch! TL;DR version is that my body is actually at the other Portal (you'll notice I saved at the edge of one), while my camera is where it was. Moving will move both in the same direction in comparison to the Portal. This may also allow the camera to "move through walls", because there's nothing block my actual body. Getting close to the front of a Portal cancels this state, while moving behind the portal switches my camera to where my body is.
Q: Actually you didn't save?
A: Then I'm doing an edgeglitch, because I didn't need any movement. Saveglitch happens by saving during an Edgeglitch.
Q: You just went superfast while crouching?!
A: I mentioned above how they tried to fix bhop. They did this by adding backwards momentum when the player goes above the speedcap. There are however ways to make this code add the wrong direction of momentum. The easier way is going backwards, the other way is, with enough momentum, going forwards, while holding backwards.
Q: What is Elevators?
A: Elevators is a mod by PackSciences that reduces the amount of loading time. I generally run Elevators for fun and praticse, while I run vanilla for actual attempts.
Q: What is Still Alive?
A: Still Alive was originally released only for the xbox version of Portal. They are 14 additional maps based on chamber ideas from the Flash Version, but much more in the style of the original game. They got ported to PC by Lever Software. A video on that can be found on the youtube channel Valve News Network!
Q: Why don't you use radio bsg?
Q: [Still alive only] Why don't you use cameras to trigger buttons?
A: I don't use radio bsg because in my opinion it's a NG+ mechanic. I don't use cameras to trigger buttons in Still Alive because that is not part of the base game and should therefore not even be a thing.
Q: Do you run Portal 2?
A: I generally dislike Portal 2 as a speedrunner. The focus went from Puzzles to Action with small puzzle sections in-between. Also movement feels very slow a drawn out. Casually I play through the game a few times a year when I feel like it. I won't stream this, as I already have a Portal 2 Playthrough on my youtube channel. I'm not into community chambers and co-op at all.
Q: How do you learn all of this stuff?
A: XeiZ has an excellent tutorial series explaining most strats done in Portal. I also analyzed lots of runs over the last few years. I routed Still Alive myself with all of that experience and seem to be doing very similar things to what other runners do.
