I may give it at a later time, but I'm not really in character creation mode at the moment. That said, back in SR3, I saw a completely unaugmented mundane showing up every augmented character (be they Awakened or Implanted) in combat. Despite some claims thrown about on these forums, I don't think it'd be impossible in SR4, just a bit difficult.
The big difference in SR3 was the combat was an opposed dice contest where the defender could potentially damage the attacker. In SR4, initiative passes matter a lot more - and augmented characters also roll more dice, attacking and defending, because boosts to Agility or Reaction add to the dice pool. With the ability to add full defense as an interrupt action, a contest between a mundane and an augmented character got even more uneven.
Still, it's not completely un-doable. Any character, even an unaugmented mundane, is murderous with a monofilament whip, trolls are tough even if they are unaugmented, and two-weapon style is extremely dangerous. High Edge is another great equalizer. Now sure, magic or augmentations can make any of those things
better - but you can still be effective against
most opposition.
