Doom Shareware and Patches
I couldn't have done this page without OldDoom.com.
Don't have Doom? Try the shareware version. Download it here. Unfortunately, there is no shareware version of Doom 2. If you have a Linux or Unix operating system, click here to get a Linux or Unix Doom source port. I have no idea how to use them, I only have Windows.
I saved the Doom 2 zip files in C:\Program Files\Games\doom2\patches and used the patches in the doom2 folder. It isn't that hard to do.
Want to buy the full version of Doom or Doom 2? I am told that you can find the lowest prices at Half.com.
