Hostile Intent, quite possibly the oldest Half-Life mod, has posted some new map pictures, as well as an interview from one of their mappers, squad. Here is a snippet from the interview.

Squad, why did you choose to build these maps for the Hostile Intent community among all the other mods in this scene? What is it about Hostile Intent that you like? (Squad is one of our testers and has first hand knowledge of the game.)

Well, when I was still trying to make maps for Counter-strike (4 years ago it seemed naturally to map for CS, I din't know of many alternatives back then anyway) I always wanted to make a
realistic setting (although I never succeeded).

Check out the images at their website.
