This account of a major criminal organisation opens with an introduction explained how it came to be: a long process during which the author refined his ideas from the original starting question of how do supervillains acquire their minions anyway? From this eventually Crimenet was spawned.
It's built along the lines of a regular corporation with a few key members for whom the operation of the organisation - rather than criminal activity itself - is their main source of income. Their core business is as an agency for supervillains, selling their services to clients, and providing resources and networking opportunities to service the supervillains' needs. They even provide legal advice or loans... after all, the average supervillain's normal interaction with a bank manager is to rob him, not to trundle round for a chat about financing his next venture!
As well as the actual provision of services, personnel and employment opportunities, it's also a membership organisation with considerable benefits for members over and above mere networking opportunities. These increase with the rank of membership that a supervillain wishes to have, neatly linking in with game mechanics to provide graded levels of benefit.
There is an interesting account of how Crimenet first came to the attention of the authorities, a cautionary tale for any over-enthusiastic hacker. Moreover, it gives ideas of how to embed Crimenet and its activities into your campaign. Then comes detailed statblocks for various 'generic' employees and agents working through or for Crimenet, from low-level henchmen and muscle up to specialists and executives, as well as named individuals complete with backgrounds and other material who are all ready to roll straight into one of your adventures. This section ends with full-blown character sheets for the highest level members of Crimenet: Mister Crime, Miss Information, Payback and Kit-Bash.
Finally, there are some notes on using Crimenet in your game (as if what you've already read hasn't been giving you ideas... well, it has me at any rate!). Assuming you are running a standard set of superheroes combatting costumed crime, Crimenet is best used as a shadowy background organisation that is revealed over time. There are notes on how different individuals within the organisation get along (or don't) and how they might make an appearance in your ongoing story. Overall, this is a fine and thoughtful resource that provides a worthy long-term adversary to weave into your game.
