This thread has become obsolete and is locked as all the download problems are now fixed
A while ago I've noticed that a lot of external download links for games on the site are not working. This is especially true for the 3D Shooting genre, where links point to the now-offline 3D Action Gamers FTP site.
To remedy that, here are some working downloads for the files which are unavailable. Hopefully you will be able to upload them to dosgames.com directly to avoid similar situations in the future.

Corridor 7: Alien Invasion

Star Wars: Dark Forces

NOTE: You might probably also want to add the files dforces2.zip and dforces3.zip which contain the optional intro and ending cutscenes respectively for the demo level.

Nitemare 3-D

Version: 2.0
Download: NITE3D20.ZIP
NOTE: Version 2.0 received a major graphics update, with most hand-drawn monster sprites replaced with pre-rendered ones. Personally I find the pre-v2.0 sprites more aesthetically pleasing but it's a matter of taste of course.
