The ancient_arena_source.zip file you have requested: Utilities / .map Files / Ancient Arena .map files - 79.26kb is not available. Perhaps try browsing all files for the game Star Trek: Elite Force II and upload any files you want to share or are missing. This is the only information we could locate:
This file contains the source .map files for the EF2 map "Ancient Arena", made by Avenger. The .zip file contains both the singleplayer and the multiplayer versions. This is intended for people who are starting to map (if they exist), so they can have a look at how things are done. Me, not having Uberradiant, wouldn't be able to give you a rating.
