All these maps runs unmodified (except the exception I will explain). The only thing I've done is to repack all the data for each game in a tex-package and creating map entries for each bsp with DEPS on this tex-package. So for example for q3dm7.bsp I created an empty map-q3dm7 that depends on tex-quake3 that contains q3dm7 (repacked pak0 and others officials) and sometime I have to rename badly named maps (for example obj_railhouse to obj-railhouse since “_” is the version separator). That's all!
Now the pictures:
1. UrbanTerror







2. Quake Live / Quake 3 Arena





3. Smokin’ Guns



4. Wolfenstein: Enemy Territory


5. Close Quarters Battle / True combat: Elite


Also, there is some time some missing textures, and many weird bugs like the #552 water bug (on tree leafs for example).
As you see some maps are overbrighten, with a 0.7 gamma it looks better:


6. Xonotic
Xonotic maps load but I did'nt manage to have textures working (only the skyboxes work out of the box):

7. Warsow
Warsow maps don't load at all (bad BSP version).
8. Exceptions
I made an exception for this map and only for this map, I modified the entities lump inside the bsp to add some spawn point. It's a community Urban Terror space-themed map named orbital, a good one to play Unvanquished.

The mapper wrote in the README he does not allow people to use his map in other projects than Urban Terror without permission, but perhaps I can ask for permission… There is a a bit work to do, add spawn points in entities, and replace some texture from Urban Terror (many textures in this map come from Urban Terror).



Now this other map is a subway-themed community map for UrbanTerror named metro (not the Tremulous metro map by KOsAD). In fact a guy ported it for Tremulous in the past, but that was a very bad port with many textures and brush issues: the guys said he has decompiled it with permission, but there is nothing to decompile here, only fix entities and use transparent textures to hide some Urban Terror themed objects…
