I watched the replay, and @ 28:45:50, [20cm]G3n appears in two places... Entering that corner near Kindergarten/Parking, and near Bond. Is that the A1 thing?
@ 28:55 It looks like some kind of Speed/boost hack...
@ 29:04, he goes WW (cutting the corner).
Then, I talk about the blue arrow wich he has, and he spectates, but there's still the other one near Bond.
Edit: Maybe I shouldn't talk about the cutting corner, since I'm contantly crashing... Wich is the worst one? Come devil and pick one.. --'
