Xbox Live Gold Games for the month of June 2018 has not yet been officially announced. Microsoft usually makes the announcement late in the month, but the announcement for Games With Gold for the coming month is still mysterious. Recently, a picture online made the rounds showing the complete Games With Gold lineup for Xbox Live Gold users.
The picture will see the complete lineup below. It includes Assassin's Creed Chronicles Russia and Smite – Battlegrounds of the Gods for the Xbox One. As far as the Xbox 360 games are concerned, these are Sonic All-Stars Racing Transformed and Lego Indiana Jones 2, which will also be playable on the Xbox One.
There is usually the possibility that this will be a fake leak one with a grain of salt. As for legality, it is too early to say anything. Smite prices do not seem to match those on the official Xbox Live Store. Assassin's Creed Chronicles has received almost all of its games on Xbox Live Gold, so Russia makes sense here.
Sonic and Lego Indiana Jones are two games that can also attend the service Sega has supported the Games With Gold series with Vanquish and Bayonetta in the past. Lego games often make it to service.
