Well... That's it.
To install the mod go to (STEAM DOWNLOAD DIRECTORY)\Steam\steamapps\sourcemods and put the insides of the RAR file into the sourcemods file and restart Steam.
If the mod isnt loading up. Try updating Source SDK 2013 to a beta called upcoming - upcoming.
This could have been good for what is a very basic few maps, despite the invisible walls and that I could easily get out of the map. I got as far as the laundrette but there didn't seem any way out after I was locked in there. It seems unfinished somehow and needs more fleshing out, I wouldn't say it was a final release really, but the bare bones are there. It needs a lot more work and testing properly I thought. Still, well done if it was a first attempt.
Yeah... You're kinda right, it does need a bit more polishing. Maybe ill remake this whole thing when I'm done making another mod
