This story makes me feel things. Horrible, wonderful things. I'm not used to this feeling, but I think I'd like to experience more of it. Please tell me you intend to continue writing this story? As much as I'm loving it so far, permit me to offer a bit of critique. In my opinion, the story would be improved if you changed the second-person POV to first-person. I say this because simply, I am not the Spy. I don't really know what he is like, I'm not aware of his background, I don't understand how his mind works, or what he thinks and feels. This... lack of a connection that I have with Spy is keeping me from being fully immersed in the story, which is important if I am the main character. Additionally, you don't really do much to tell us what we are like. It's mostly a play-by-play of events, with predictable responses (fear, etc) that aren't necessarily distinctive to the Spy. However one might interpret them, the TF2 cast has a lot of personality, and I'm not seeing much of that here. Is this bad? No, the story certainly holds it's own more than well enough as it is. But I think if you switched to first-person, you could retain everything without causing that dissonance between reader and protagonist. I will still be able to involve myself emotionally with the story even if it's not ME that is experiencing it all first hand. That's pretty much the only thing I didn't like. What I DO like is your Engineer. It's rare to find an antagonist Engineer that isn't either a jerkass Engie or a "well someone has to be the rapist in this story" Engie. I'm not a fan of either of those, but yours is glorious. The Engineer is a mercenary who chooses to use his talent, creativity, and education to MURDER PEOPLE in exchange for a multi-million dollar salary. Why don't we see more of that in fanfiction? This Engie has a screw loose and is totally comfortable with it; revels in it, even. It gives me the good kind of chills.
