In order to use this book, you have to have either Champions or Danger International. It wouldn't hurt to have both.
If there can be comics about super-agents, there can also be gaming campaigns. That's where this supplement comes in. Super-Agents is a campaign supplement with guides on running, well, super-agents. Running them as player-characters, as the focus of an ongoing campaign. If you don't want to run a regular super-agents campaign, the materials here may also be used as guidelines for setting up large agent groups as NPCs in a campaign.
