The wolf_mp1_noinstall.zip file you have requested: Official Releases / Maps / Trench Toast - 3.33mb is not available. Perhaps try browsing all files for the game Return To Castle Wolfenstein and upload any files you want to share or are missing. This is the only information we could locate:
Here's the first official "add-on" map that was just as a christmas present from Gray Matter, Nerve Software and Activision! This map is not available in the current retail version, however this map is available in the RTCW Multiplayer Demo (no not the Tests) that was just released! Here's the description: Trench Toast is a terrain-based map that features lots of fortifications and sniper positions, as well as a number of canals and trenches for players to use as cover. The new map supports far more players--up to 32--than the original checkpoint map included in Wolfenstein, and it features lots of hidden areas and a wide-open style rather than the streets featured in the other checkpoint map.
For anyone that is having problems installing the new TrenchToast map (particularly server admins that have copied their Wolf directory to multiple machines), we have created Wolf_MP1_NoInstall.zip which allows you to simply extract the necessary files to your Wolfenstein directory, regardless of original install process or install location. This should only be necessary for people that did not go through the normal install process for the retail game.
