I'm not a screenwriter but awhile back (about 3-4 months ago) I made my first screenplay that was about Halo ODST, for fun and also its not finnished, it might never be done to be honest. But I was curious on what you guys might think about it and what feedback you guys would give?

Just remember this is my first screenplay, so just be prepared on reading something pretty bad...

Edit: it's meant to be a short story btw.
