Mod library
Towers, tilesets, props, enemies, sounds, maps and whole campaigns, made by players and loaded straight into the game.
Being built
Each game will get its own section here. You'll sign in with your forum account, so your forum profile is also your modding profile: what you've uploaded, and what you follow.
Subscribe to a mod and the game downloads it for you next time it opens, with no files to move by hand.
