Came across an interesting blog today by the name of World of Level Design, a blog maintained by Level Artist Alex Galuzin. There’s literally an abundance of tutorials and articles scattered throughout the site focusing use with Hammer Source and Unreal 3 engines – if you’re a Left 4 Dead fan, you will definitely want to check these out.
Also of interest Alex made available some maps and tutorials you can download at anytime from http://www.alexgaluzin.com. Happy Friday! Enjoy. [Learn more]
