"We'll have to deal with something within the political rules that allow us to do that," Torben Ellert, game designer on Hitman: Absolution told us. "We're interested in featuring community contracts so that we avoid that whole wasp's nest."
The way to do that will be for the community to decode the file numbers of contracts after the game's launch. Contract IDs begin with a two-digit number, determining their platform (currently 03- PC, 05- Xbox, 07- PS3), with the following set of digits expressing rules of the scenario.
"[Contracts] was built in a way for people to asynchronously share things," said Ellert. "The trick is you have to do it yourself. You have to be able to pull it off yourself."
Update: To stress, codes can't simply be swapped across platforms. Players on separate platforms will need to complete the aspects of a contract to make it live on that platform. The contract ID simply gives the blueprints for a scenario's rules.
