You might consider really playing to that then. Again, this is a not-very-serious sci-fi RP, there's no reason to ground your character in reality. I play a walking tank, for crying out loud. You could have some sort of Adam Jensen-esque black ops character with cybernetics that let him cloak himself and stuff. We don't really have a subterfuge focused character, you could totally go with a Starcraft Ghost style or something.

Basically it just looks like you're drawing a lot on science-reality and not much on science-fiction.
