Last week the Dota2 community alerted us to the fact that the ‘Timebreaker’ weapon submission for Faceless Void mirrored the design of a weapon found in the MMO ‘Aion.’ After investigating the issue we discovered that the item was a violation of Workshop rules. In accordance to our Workshop copyright policies we are taking the following actions: The contributor of the violating asset will receive an extended Steam Community ban. We have also replaced the Timebreaker’s model with a new model designed by the Dota2 team that we feel serves as an attractive replacement.
