A conversion of the tunnel o' love from SiN, I don't know the original map so I don't know how close this one is. The tunnel effect is cool. There are a few technical problems with the main .shader effect that kind of undermine some of the moving train illusion. For instance, a surfaceparm nomarks would have stopped unmoving burn marks being left on an otherwise moving wall. It doesn't play that great, but its not bad either.
A fun map with a great effect, could have been finished off a bit better.
