Robert Duffy from Id Software has updated his .plan to clear up a bit of confusion initially surrounding the Return to Castle Wolfenstein tools SDK that was released yesterday. Here is a snip:

To clear up a bit of confusion, what we released yesterday was the level editing tools and not the full SDK for Wolfenstein. Everything is there to create both single-player and multi-player maps. Also included is Escape ( from single-player ) and Beach ( from multi-player ) for reference.

The source code will be available soon.
