The Swamp Theme is a pack of swampy assets for you to use in your custom Team Fortress 2 map! We've assembled some of the best content creators at TF2Maps.net and forced them to make this
set of cool models, textures, particles, and more for you to enjoy. The Swamp pack is now in the game and ready for use!
But not all of it was shipped with TF2, which you can see highlighted below.
