Transformers Earth Wars first introduced Power Cores in October 2017 as a way to enhance bots and base defense. As described by the developers, Power Cores can be used “for a strategic advantage in battle or increase the chances of a successful defense” of your base.
Power Cores can be obtained through a special campaign called the Story of Nebulos which involved five battles and looks to educate the player on what some of the different Power Cores can do during the battles. By defeating all five bases you unlock the ability to build you Power Core Lab which then allows you to Equip, Manage and Fuse Power Cores on bots and bases.
