The Teleporter that Takes you to Xen

Go bunnyhop in HL:S

I know it’s not possible, but since it’s source can’t you use the same techniques as hl2? like ABH or stuff like that?

No, otherwise we’d use that. You have regular bunnyhop, but you don’t gain any speed. There’s only one glitch that’s any useful, which is the Vertical Object Boost glitch, but other than that, it’s a handicap HL1.
