We want to address your concerns regarding the ability to complete the collection.
For now you can't complete the "The Transformers: The Movie 35th Anniversary" collection after receiving all freely obtainable same-name containers. In order to do it you have to purchase additional containers to complete the collection in the Armory or Premium Shop.
However, we plan to continue our partnership with Hasbro within the Transformers franchise. During the next stage of collaboration, you will be able to resume receiving the elements of the "The Transformers: The Movie 35th Anniversary" collection and complete it for free.
Details on the following stages of collaboration will be announced later.
