Shadowrun, Fourth Edition Compatability

We’ve received a number of questions about which of the sourcebooks and rulebooks from Shadowrun First, Second, and Third editions are compatible with the new Fourth Edition. The simplest way to answer this is to say that it depends on how much rules material a given book has. We completely revamped the rules system in SR4, so rules from previous editions are no longer compatible. Source material, on the other hand—meaning plot, setting, and background material—is largely compatible with SR4, as we have not made any significant changes to Shadowrun’s past history. We did, however, jump the timeline ahead 5 years to 2070, primarily to introduce new Matrix technology, so some things may have changed in the meantime.

These books are primarily source material, and are largely unaffected by the SR4 changes.

These books have some rules material that is no longer relevant, but the source material still is. Many of these are adventures—the plot is still usable, but any game mechanics and NPCs will need to be adjusted by the GM.

These books are primarily (90%+) rules, so most of the material will not work with SR4. A new set of core rulebooks—Street Magic, Arsenal, Augmentation, and Unwired, among others—replace these books.
