The entaliens.zip file you have requested: Skins / Star Trek / Enterprise Aliens Pack 1 - 2.86mb is not available. Perhaps try browsing all files for the game Star Trek: Elite Force and upload any files you want to share or are missing. This is the only information we could locate:
Three skins of Enterprise aliens: Vosk, illyrian Captain, and Silik. Some of you may remember there was a Silik skin posted on EFFiles once before, well this is an updated version of that skin by the same author, who is now part of the NX-01 mod team.
