Access
Codes
This
page contains the copy protection codes needed to enter
X-COM: UFO Defense v1.2 (or UFO: Enemy Unknown v1.2) and earlier. You do
not need these codes if you use the official Microprose v1.4 patch. The patch
eliminated the need for the access codes, but it also damages the music and
sound effects in the game. This is the reason I make the codes available. You can get an unformatted
version of these codes at the download page.
