I could beat the game on Secret Agent pretty easy, some levels almost only using the PP7. Most levels are crazy hard on 00 Agent though, I guess because they take out the auto aim. To this day I still can't beat the Control Center, when you have to protect Natalya.
That video is probably an emulation though, I've never tried GE on my PC, but I've seen a couple mod sites with custom levels and stuff.
