Faith was my contribution for the single-player modification / map-pack called "Issues". Issues was meant to be the successor to PQL (Project Quantum Leap) and thus the goal was to have a map pack created by as many different people as possible, to be as incoherent like hell.

Despite the minor amount of publicity, Issues was pretty well received and overall people seemed to like it.

For me personally, Faith was a little experiment; I wanted to see what I could create using just Half-Life textures. Though it turned out to be a pretty OK map, I quickly ran out of inspiration, thus making it visually not as impressive as it could've been.

Despite the problem with inspiration and using just the Half-Life textures, it came out pretty well and people seemed to like it. (Tough some thought the combat was too much.) If you're interested in playing a few interesting Half-Life maps then download Issues. Asides Faith, there are quite a few worthy maps in there.
