First thing I've created in Hammer in about three years, and as such it's a test to get used to everything once again. This is a small recreation of the Spencer Mansion from the first Resident Evil game. It's not accurate (or finished, for that matter) but I'll be adding and building on it as I test out more things.
Textures used come from the AbsolutVodka and ZillaFinal wads for Day Of Defeat.
If you need further help on improoving your map, you could head to THIS link. It's the first RE1 mansion remake in Half-Life.
Take a look at it with BSPViewer, or decompile it with WinBSPc for learning purposes.
