Astute memory. I'm not going to lie, that version of the map you remember was a part of a group project, and I did not request permission to use the vmf; those fences you saw were not my work. When I was doing my second round of touchups for this HRCS project, I redid the map from scratch, so that all the handiwork seen here is only Valve's and mine.

This actually applied to canals maps 01 and 01a as well. In fact, all the way up until 07 was a part of that project originally, but everything after this map (02), was my work. I have also completely redone all canals maps from 01 to 07 from scratch.

The project was (is?) called Half-Life 2: Lambda Revision and is (was?) being developed by a team who call themselves Eikia Studio. I left the team on my own accord because I deemed myself as too unreliable due to being too busy during the day due to work, and it felt scummy to keep it up, hence this vanilla (in comparison) version that also matches my vision for Half-Life 2: HRCS better.

I swear there was a different version of this that had like a fence or something on that wall you see at the start of the map. What happened to it?
