  Do add-on campaigns need to be written to work with the SCP? I'd like to play a new camaign, but haven't seen any saying it requires SCP? Are there any that rival the main campaign in story, length and detail? Looking for something to keep me playing for a week, or two at least.

The ideal goal is that nothing needs to be rewritten to work with the SCP. However the only absolute is that we won't break :V:'s missions.

The result is that many of the retail campaigns do work on SCP but a noteable few are broken.

As for SCP only campaigns Skippy's campaign list has a whole section devoted to SCP only campaigns.

Either Sync/Transcend or Derelict fit the description of something that will keep you playing a while.
