I am Collin Eddings, or perhaps known as “Rubber Ducky,” a Source engine mapper. I’ve been mapping since June of 2008 and have only gotten better since. I started out with some awful blocky maps for Garry’s Mod (gm_ultrahill, gm_flatwater2009), then slowly improved and worked hard to make prettier, funner, more optimized maps.
At the time of writing this, I am currently working on the full remake of The Stanley Parable.
Anyway, enjoy my old tutorials/maps.
