Oh wow, this is very well done.
-I'm not much of a shooter person, but those are some cool and fun moves. Running+sliding quickly became my favorite move. These kind of actions made your project stand out a bit more from the rest among its genre.
-Another good point is the character's quotes. They are well delivered (for example. the many "out of ammo" quotes create a good sense of urgency)
Moving in this game is great, although turning around and moving feels a bit less fluid compared to the rest (although if that's be the way you intended to do it it works)
I really liked the animations, in particular the melee takedowns and the red barrels exploding.
I think the camera being a bit smoother would benefit this game.
Overall it feels like a very well polished project. Good job!
