I remember pushing the limits of "fast" gameplay with really fast suit mode switching, and before that modifying the suit values in an .ini file in the game directory to have flash-level speed and infinite energy. It's a shame that they dumbed it down in the sequels so much for the consoles. And that the game became so much worse _as a game_ (even if my first play through had my jaw hit the floor when I entered the alient ship) after the midpoint. Punching through plywood shacks for an ambush, jumping high for a grenade, using speedmode to get a flank (which the AI would be unaware of - if they couldn't see you!). Yeah it was a good time.
