Absolutely awesome work posted on this page!
I'm floating around id Tech 4 community lately, working on two projects based on this engine. But here's something completely unrelated to GoldSrc and id engines. A little tile-map based game I'm coding from scratch in C++ using SFML library. Player texture is a placeholder, level aesthetics were designed by my roommate (aiming for dirty, retro looks), and there's not much of game logic yet, but it's damn awesome to get something working!
