Contrary to Wolfenstein: Enemy Territory, Return to Castle Wolfenstein doesn't support HTTP Downloads in-game. This is where this little application comes in handy. It's a lightweight tool, written in .NET that automatically closes down the game, downloads the map from HTTP and afterwards reconnects you to the server you were playing on, whenever a PK3 file is missing in your 'main' folder!

It works on all versions of RtCW, including 1.0, 1.33 and 1.4, as long as the in-game download system is enabled on both client and server. (sv_allowdownload 1 & cl_allowdownload 1)
