No I am sure I / we don't have those installed. I just noticed that the zip as you mentioned has these files in it. I'm sure that'll solve things, but it doesn't fit our quake 3 workflow! :D (the server has all the maps as pk3s only, and we download each new from it as we go through them.)

I'm only getting a single missing texture warning about /liquids/pool3d_6e.tga - no visual impact. Just to confirm, you do have both map-media-wolf.pk3 and map-media-genstart2.pk3 in your baseq3. These PK3's are part of the download.

As to PeaceFrog's comments about this being an initial effort, the map was completed close to 2 years ago and originally intended for the Generations Arena mod. It was only given a standalone release because several people asked me to release it as such. It's designed to mimic the "home" grounds of the 5 classes in Generations Arena, so the detail leves are low in some areas by design.

I'm missing a few textures though? Could be just my system though.

I like the moving block to the bfg. Nice touch.
