I loved it! Have you considered making maps for roleplay? Adding a few extra houses and removing the game-ending function on the train would make it even better!

Will this work with hl2 or do you need ep 2?

The outside looks a lot like one of the maps in the Missing Information Mod. This looks a lot better though!

This hardly looks on the hl2 leak map i forgot the name of it this one is worked out and seems to look pretty good
