This collection should have all TTT maps. Simply subscribe to all of them and you should be good to go, assuming you have CS:S installed, some maps might need it.

Player models, TTT related addons and other addons for my private TTT server. This collection also has a linked collection to all the maps that you need.

None of these maps are made by me, i just made a collection so its easier for my friends to download the maps to use on my private server. NOTE: you need CS:S files for some of the maps! If you don't have CS:S on steam be sure to search on google / youtube
