World of Tanks Supertest has already received the final model for the Italian Tier IX Heavy Tank tech tree, Progetto C50 mod. 66 also known as Progetto 66 in-game. The tank was still missing all the details, and while it still in SD, the final HD version should be ready too.
The vehicle has received substantial changes in the last Supertest iteration, and while it does have a nice look to it, we still don’t know how it will play in the current meta of World of Tanks. For now, you can appreciate the full detailed model before it is officially released.
The Italian Heavy Tank branch is due to be released with Update 1.11.1, in late January 2021, so we still have a while before we can play them.
