A collection of all my Sonic 3D Blast level recreations for use in Survival Mode, while the game will report the addons as conflicting, they do work fine with each other, the "conflict" comes from how L4D2 treats sound.cache files, as well as the fact that I do need to duplicate some files between the addons so that they work as standalones.
