Does mods for HITMAN 3 work for HITMAN World of Assassination?
Welcome to the Community. 
HITMAN World of Assassination is the rebranded version of HITMAN 3 that functions as a single platform for the entire trilogy. It includes the full base games for Hitman (2016), Hitman 2 (2018), and Hitman 3 (2021).
If you’re playing Hitman 3 from the World of Assassination rebrand, then yes, the Hitman 3 customisations at Wand will work with it.
If you have any more questions about this game, please feel free to use the official thread here: Hitman 3 Cheats and Trainer for Steam.
Have a great day!
