KRE-O Transformers was a 2014 event created by the user Games to sponsor the KRE-O Transformers: Age Of Extinction playsets.
The game had two teams, Optimus Prime and Lockdown. The goal of the game was to run around in the city to find all of the pieces that your team needed. If you seen a piece that was on the enemies side you could shoot it with your blaster so then the piece would disappear and make it to where it would take longer for it to respond on the map, making it more difficult for the opposite side. When you collected all of the pieces on Optimus Prime's team you would win a KRE-O Optimus Prime Helmet, and if you collected all of the pieces on Lockdown's team then you would win a KRE-O Lockdown Helmet. If you failed to collect all of the pieces for your team then simply you would earn a participation prize which was KRE-O Bumblebee's Helmet. Then the game would simply restart again after the round ended, and would randomly assign players to different teams for the next round.
