There's a new Robots in Disguise mini-game. You control Bumblebee, Sideswipe, Grimlock and Strongarm to collect enough energon and reach "safe zone" in the center of the map, where they combine and use superpowers to defeat Galvatronus (you can use powers of the bots in the safe zone when you're playing as other bots, too). After finishing the game you get a random upgrade for a character's superpower (each has 2 upgrades, so you have to finish it 8 times to be maxed).

Galvatronus is the boss of this game and not Menasor. Interesting...

This seems fun, might try it out.
