It's not just "restrictions" we've been discussing in the PS4 thread, Euler13. It's special conditions.
From now on we're going to allow contract-creators to impose a maximum of two special conditions. These can be almost anything that enhance the challenge or the roleplaying immersion of the contract, without creating too much confusion.
For example, my current active contract, set in Paris, has two such conditions:
The player must start the mission on the red carpet.
The player must use an un-silenced shotgun for its two shotgun kills, because the assassination is supposed to be loud and dramatic.
I'm not sure if @Silverballer is doing exactly the same thing here, but I thought I'd give the pertinent information that you and your fellow Xbox players have missed.
