From the PocketMod back cover:
There is a secret world behind the real. A world of the Great Game -- filled with covert agents, double-crosses, and attacks against humanity.
You and your friends prevent this from spilling over to the real world. Not as suave, highly-trained agents, but as their handlers.
SPECTRUM is looking for a new Control. Will you prove your agents superior to the others? Become the next Controller for the Agents of SPECTRUM
