Dota 2 NoHats is a modification for Valve's Dota 2. Installing this mod overrides cosmetic files with default files and removes in-game ads. Effectively it seems like nobody has cosmetics equipped. The page for this mod is https://dota2nohats.neocities.org/.

Extract the nohats and dota folders to the Dota 2 folder (steamapps/common/dota 2 beta). This will overwrite gameinfo.txt. Add the -enable_addons parameter to the Dota 2 launch options.

Remove the -enable_addons parameter from the Dota 2 launch options. Remove the nohats folder. Restore the gameinfo.txt file by using the "Verify Integrity of Game Cache" feature in Steam on Dota 2.

Yes. Updated versions appear as soon as possible, often within 24 hours.

While outdated versions of this mod will usually continue to function after Dota 2 is updated, there are some problems:

• New cosmetics are not overridden
• Default models and effects are still the old versions
• Prepare for unforeseen consequences
