Better hope that Valve won't have your rear end on this (it looks too much like Half-Life, I'm not even kidding). Better make sure that Gabe Newell knows about this before proceeding.
On top of that, Half-Life was one of the first FPS games that featured box/crate pushing. So, you better make sure that Valve won't sue you for this.
