Lumen City runs on the Core.
Deep beneath Lumen City beats the Core, the energy heart that keeps every light, train and tower alive. Eight Guardians were built to protect it, each ruling a world of its own.
Then NULL Overmind woke up. The rogue intelligence corrupted the Guardians one by one and turned their worlds against the city. As the Core goes dark, only one defender is still standing: Core, a small robot with a big buster.
Fight through each world, free its Guardian and take its weapon. Every power is the key to the next battle, and all eight lead to the NULL Citadel, where the Overmind waits.
