Hello!
Archlife is my blog about modern architecture + halflife
It's not possible to download the tutos nor Vals map now because the link is not working. If you're interested, I can send them to you via Email.
The point in ArchLife is not to create INCREDIBLE OUTSANDING HL maps, but to discover existing buildings by visiting them in HL engine. I haven't seen any building I modeled in Worldcraft/Hammer in real but after having fought sooooo many times inside them I know them better than anybody.
As a professional architect, I used the HL engine to explore new designs during the sketch level and I must say this was pretty efficient...
When I see a building now, I can't stop myself thinking about its 'fightability'
