The Best FPS of All Time - Ultimate DOOM + Brutal Doom
4This is a short demonstration of the best first-person shooter of all time. The classic FPS Ultimate DOOM rendered in GZDoom's engine, with the Brutal Doom mod. Here's where to get everything:
GZDoom - open source DOOM engine for Windows and Mac with better graphics:

Brutal Doom - quite possibly the best mod for the DOOM games:

To play the DOOM games you will need the WAD files that come with the games, as these files contain all of the game's content (levels, weapons, etc). Since these are still copyrighted, I will paste links to get them from Steam below, however you can also get them from Amazon, some local stores, and various other online sources.
