Warehouse Firefight

I mostly mapped for TFC and this is my first try at a HL map. Im stll learning the Half-Life entities so cut me some slack ;). If I finish this project this map will be part of the first of 2 or 3 maps in the story. The begining and the end of the map are not exactly how they will be if I finish it.

--The Story--
You are a Gordan Freeman type dood who was left for dead with Barney in a locked room of a warehouse. The warehouse is really just a cover for a Top-Secret splinter government research facility in London that is working on experimental weapons. They tried to kill you because you stumbled onto their secret plans at making a weapon 10,000 times more powerful than a nuclear warhead. You must fight your way through the warehouse complex into the underground Secret Labs to get evidence so you can tell the world about this weapon and head off another arms race. Once you get to the labs you find out that one of their experiments has gone haywire and has opened a rift into our dimension from an alien world. Aliens are pooring into the underground facility and are getting ready to begin an all out invasion of earth. You must fight your way through the aliens and make your way to the few remaining scientists and get them to help you set off one of the smaller doomsday weapons. The explosion in the heart of the lab deep beneath london should destroy all the aliens and close off the rift.

--Progress--
So far I finished most of the warehouse level. You can make your way all the way to the room that will end up being the gateway to the underground labs level. I need to sort out the entities a little still but the architexture is pretty much done.

--Hint-- You need to find a way out of the first building and out the gate to get into the second building :). Dont tell after you figure it out I want to see if it's too easy or too hard.

So please look it over and let me know if I should finish it or whatnot since I been working on other stuff lately. Since its my firt try at Half-Life I would like to get a lot of input about it.

Enjoy, Thanks
