DeNA Games has announced an all new event for their “Transformers: Legends” game titled “Cosmic Rust”!
The evil Decepticons come across a long forgotten Autobot world  on their way to Cybertron. Curious about the dead world they decide to land on it for a closer look and in doing so they discover a powerful weapon… the Lightening Bug!
Megatron then takes the weapon to use against the Autobots but ends up inflicting more pain on himself than on Optimus.
