I found this version on web, but today the link is offline.
I was thinking while download it that was a version with final level(Fifth level), but unhappily i was wrong.
Modifications on this version:
1-Went corrected some textures that were missing on final released.
2-Some soldiers were changed on the level 4.
3-It was modified the end of the level that would be the level 5.
Notes:
1-The levels 1 to 3 are the same of the final released that is on RTCW's website maps reviews.
2-I believe that this version is for collectors and curious.
3-Link to download for this version(16.11MB): http://www.megaupload.com/?d=RS4SZE5O
