Any special abilities

Only the perks you get.

This is not Skyrim, your not a dragonborn

With the right combo of perks you can be tony freakin stark, or the freakin batman, or freakin wolvereen on steroids,

And that's not counting the really crazy op builds.

So we can put the rumors aside that we are not a sinth. I understood we were not dragonborn but it was a theory at 1 point

So far I have not seen any in game indication you were anything but human apart from some perks and some weirdness at tranquility lane.

After stumbling on a spoiler a few days ago at Steam I was wondering if we'd be a synth. If so, I had my character name at the ready - Roy Batty.
