This September is one to remember for Transformers fans everywhere as DeNA rolls out a series of weekly episodes and new content including PvP for Transformers: Legends, a mobile card battle game inspired by the Transformers universe in the 1980s cartoon series.

Through September 10, the One Shall Fall episode commences pitting none other than Optimus Prime against Megatron in the ultimate showdown! This is the first Transformers: Legends episode to feature Optimus Prime and the first time that Optimus Prime is an Ultra Rare (Rarity 5) card.

In this episode, the conflict between the Autobots and Decepticons has come to a head and Megatron is leading an all out assault on Autobot City. It’s up to you to take on the Autobots and help Megatron overwhelm their forces to finally face off with Optimus Prime. The One Shall Fall episode also features familiar faces with the support of all-star characters Ironhide, Bumblebee, Shockwave, Jazz and Starscream.

The all-star Transformers: Legends episodes don’t stop there as September is set to bring another action-packed episode right after One Shall Fall featuring the monstrous Dinobots.

September also gives players the chance to take on other Transformers: Legends masters with an all-new PvP episode.
